1# Makefile for zlib
2# Borland C++
3
4# This version of the zlib makefile was adapted by Chris Young for use
5# with Borland C 4.5x with the Dos Power Pack for a 32-bit protected mode
6# flat memory model. It was created for use with POV-Ray ray tracer and
7# you may choose to edit the CFLAGS to suit your needs but the
8# switches -WX and -DMSDOS are required.

1.TH ZLIB 3 "11 March 2002"
2.SH NAME
3zlib \- compression/decompression library
4.SH SYNOPSIS
5[see
6.I zlib.h
7for full description]
8.SH DESCRIPTION
9The
10.I zlib
11library is a general purpose data compression library.
12The code is thread safe.
13It provides in-memory compression and decompression functions,
14including integrity checks of the uncompressed data.
15This version of the library supports only one compression method (deflation)
16but other algorithms will be added later and will have the same stream interface.
17.LP
18Compression can be done in a single step if the buffers are large enough
19(for example if an input file is mmap'ed),
20or can be done by repeated calls of the compression function.
21In the latter case,
22the application must provide more input and/or consume the output
23(providing more output space) before each call.
24.LP
25The library also supports reading and writing files in
26.I gzip
27(.gz) format
28with an interface similar to that of stdio.
29.LP
30The library does not install any signal handler. The decoder checks
31the consistency of the compressed data, so the library should never
32crash even in case of corrupted input.
33.LP
34All functions of the compression library are documented in the file
35.IR zlib.h.
36The distribution source includes examples of use of the library
37the files
38.I example.c
39and
40.IR minigzip.c .
41.LP
42A Java implementation of
43.IR zlib
44is available in the Java Development Kit 1.1
45.IP
46http://www.javasoft.com/products/JDK/1.1/docs/api/Package-java.util.zip.html
47.LP
48A Perl interface to
49.IR zlib ,
50written by Paul Marquess (pmarquess@bfsec.bt.co.uk)
51is available at CPAN (Comprehensive Perl Archive Network) sites,
52such as:
53.IP
54ftp://ftp.cis.ufl.edu/pub/perl/CPAN/modules/by-module/Compress/Compress-Zlib*
55.LP
56A Python interface to
57.IR zlib
58written by A.M. Kuchling <amk@magnet.com>
59is available from the Python Software Association sites, such as:
60.IP
61ftp://ftp.python.org/pub/python/contrib/Encoding/zlib*.tar.gz

70.LP
71The data format used by the zlib library is described by RFC
72(Request for Comments) 1950 to 1952 in the files:

75<a name="Introduction"><h2> Introduction </h2>
76 The 'zlib' compression library provides in-memory compression and
77 decompression functions, including integrity checks of the uncompressed
78 data. This version of the library supports only one compression method
79 (deflation) but other algorithms will be added later and will have the same
80 stream interface.
81 <p>
82
83 Compression can be done in a single step if the buffers are large
84 enough (for example if an input file is mmap'ed), or can be done by
85 repeated calls of the compression function. In the latter case, the
86 application must provide more input and/or consume the output
87 (providing more output space) before each call.
88 <p>
89
90 The library also supports reading and writing files in gzip (.gz) format
91 with an interface similar to that of stdio.
92 <p>
93
94 The library does not install any signal handler. The decoder checks
95 the consistency of the compressed data, so the library should never
96 crash even in case of corrupted input.

100<a name="Utility functions"><h2> Utility functions </h2>
101 The following utility functions are implemented on top of the
102 <a href="#Basic functions">basic stream-oriented functions</a>.
103 To simplify the interface, some
104 default options are assumed (compression level and memory usage,
105 standard memory allocation functions). The source code of these
106 utility functions can easily be modified if you need special options.

133<font color="Blue"><dt> int <a name="compress">compress</a> (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen);</font>
134<dd>
135 Compresses the source buffer into the destination buffer. sourceLen is
136 the byte length of the source buffer. Upon entry, destLen is the total
137 size of the destination buffer, which must be at least 0.1% larger than
138 sourceLen plus 12 bytes. Upon exit, destLen is the actual size of the
139 compressed buffer.<p>
140 This function can be used to <a href="#compress">compress</a> a whole file at once if the
141 input file is mmap'ed.<p>
142 <a href="#compress">compress</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not
143 enough memory, <a href="#Z_BUF_ERROR">Z_BUF_ERROR</a> if there was not enough room in the output
144 buffer.<p>
145

147<dd>
148 Compresses the source buffer into the destination buffer. The level
149 parameter has the same meaning as in <a href="#deflateInit">deflateInit</a>. sourceLen is the byte
150 length of the source buffer. Upon entry, destLen is the total size of the
151 destination buffer, which must be at least 0.1% larger than sourceLen plus
152 12 bytes. Upon exit, destLen is the actual size of the compressed buffer.
153 <p>
154
155 <a href="#compress2">compress2</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not enough
156 memory, <a href="#Z_BUF_ERROR">Z_BUF_ERROR</a> if there was not enough room in the output buffer,
157 <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the level parameter is invalid.

159
160<font color="Blue"><dt> int <a name="uncompress">uncompress</a> (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen);</font>
161<dd>
162 Decompresses the source buffer into the destination buffer. sourceLen is
163 the byte length of the source buffer. Upon entry, destLen is the total
164 size of the destination buffer, which must be large enough to hold the
165 entire uncompressed data. (The size of the uncompressed data must have
166 been saved previously by the compressor and transmitted to the decompressor
167 by some mechanism outside the scope of this compression library.)
168 Upon exit, destLen is the actual size of the compressed buffer. <p>
169 This function can be used to decompress a whole file at once if the
170 input file is mmap'ed.
171 <p>
172
173 <a href="#uncompress">uncompress</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not
174 enough memory, <a href="#Z_BUF_ERROR">Z_BUF_ERROR</a> if there was not enough room in the output
175 buffer, or <a href="#Z_DATA_ERROR">Z_DATA_ERROR</a> if the input data was corrupted.

180
181<font color="Blue"><dt> gzFile <a name="gzopen">gzopen</a> (const char *path, const char *mode);</font>
182<dd>
183 Opens a gzip (.gz) file for reading or writing. The mode parameter
184 is as in fopen ("rb" or "wb") but can also include a compression level
185 ("wb9") or a strategy: 'f' for filtered data as in "wb6f", 'h' for
186 Huffman only compression as in "wb1h". (See the description
187 of <a href="#deflateInit2">deflateInit2</a> for more information about the strategy parameter.)
188 <p>
189
190 <a href="#gzopen">gzopen</a> can be used to read a file which is not in gzip format ; in this
191 case <a href="#gzread">gzread</a> will directly read from the file without decompression.
192 <p>
193
194 <a href="#gzopen">gzopen</a> returns NULL if the file could not be opened or if there was
195 insufficient memory to allocate the (de)compression <a href="#state">state</a> ; errno
196 can be checked to distinguish the two cases (if errno is zero, the
197 zlib error is <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a>).
198 <p>
199
200<font color="Blue"><dt> gzFile <a name="gzdopen">gzdopen</a> (int fd, const char *mode);</font>
201<dd>
202 <a href="#gzdopen">gzdopen</a>() associates a gzFile with the file descriptor fd. File
203 descriptors are obtained from calls like open, dup, creat, pipe or
204 fileno (in the file has been previously opened with fopen).
205 The mode parameter is as in <a href="#gzopen">gzopen</a>.
206 <p>
207 The next call of <a href="#gzclose">gzclose</a> on the returned gzFile will also close the
208 file descriptor fd, just like fclose(fdopen(fd), mode) closes the file
209 descriptor fd. If you want to keep fd open, use <a href="#gzdopen">gzdopen</a>(dup(fd), mode).
210 <p>
211 <a href="#gzdopen">gzdopen</a> returns NULL if there was insufficient memory to allocate
212 the (de)compression <a href="#state">state</a>.

217 Dynamically update the compression level or strategy. See the description
218 of <a href="#deflateInit2">deflateInit2</a> for the meaning of these parameters.
219 <p>
220 <a href="#gzsetparams">gzsetparams</a> returns <a href="#Z_OK">Z_OK</a> if success, or <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the file was not
221 opened for writing.
222 <p>
223
224<font color="Blue"><dt> int <a name="gzread">gzread</a> (gzFile file, voidp buf, unsigned len);</font>
225<dd>
226 Reads the given number of uncompressed bytes from the compressed file.
227 If the input file was not in gzip format, <a href="#gzread">gzread</a> copies the given number
228 of bytes into the buffer.
229 <p>
230 <a href="#gzread">gzread</a> returns the number of uncompressed bytes actually read (0 for
231 end of file, -1 for error).
232 <p>
233
234<font color="Blue"><dt> int <a name="gzwrite">gzwrite</a> (gzFile file, const voidp buf, unsigned len);</font>
235<dd>
236 Writes the given number of uncompressed bytes into the compressed file.
237 <a href="#gzwrite">gzwrite</a> returns the number of uncompressed bytes actually written
238 (0 in case of error).
239 <p>
240
241<font color="Blue"><dt> int VA <a name="gzprintf">gzprintf</a> (gzFile file, const char *format, ...);</font>
242<dd>
243 Converts, formats, and writes the args to the compressed file under
244 control of the format string, as in fprintf. <a href="#gzprintf">gzprintf</a> returns the number of
245 uncompressed bytes actually written (0 in case of error).
246 <p>
247
248<font color="Blue"><dt> int <a name="gzputs">gzputs</a> (gzFile file, const char *s);</font>
249<dd>
250 Writes the given null-terminated string to the compressed file, excluding
251 the terminating null character.
252 <p>
253 <a href="#gzputs">gzputs</a> returns the number of characters written, or -1 in case of error.
254 <p>
255
256<font color="Blue"><dt> char * <a name="gzgets">gzgets</a> (gzFile file, char *buf, int len);</font>
257<dd>
258 Reads bytes from the compressed file until len-1 characters are read, or
259 a newline character is read and transferred to buf, or an end-of-file
260 condition is encountered. The string is then terminated with a null
261 character.
262 <p>
263 <a href="#gzgets">gzgets</a> returns buf, or <a href="#Z_NULL">Z_NULL</a> in case of error.
264 <p>
265
266<font color="Blue"><dt> int <a name="gzputc">gzputc</a> (gzFile file, int c);</font>
267<dd>
268 Writes c, converted to an unsigned char, into the compressed file.
269 <a href="#gzputc">gzputc</a> returns the value that was written, or -1 in case of error.
270 <p>
271
272<font color="Blue"><dt> int <a name="gzgetc">gzgetc</a> (gzFile file);</font>
273<dd>
274 Reads one byte from the compressed file. <a href="#gzgetc">gzgetc</a> returns this byte
275 or -1 in case of end of file or error.
276 <p>
277
278<font color="Blue"><dt> int <a name="gzflush">gzflush</a> (gzFile file, int flush);</font>
279<dd>
280 Flushes all pending output into the compressed file. The parameter
281 flush is as in the <a href="#deflate">deflate</a>() function. The return value is the zlib
282 error number (see function <a href="#gzerror">gzerror</a> below). <a href="#gzflush">gzflush</a> returns <a href="#Z_OK">Z_OK</a> if
283 the flush parameter is <a href="#Z_FINISH">Z_FINISH</a> and all output could be flushed.
284 <p>
285 <a href="#gzflush">gzflush</a> should be called only when strictly necessary because it can
286 degrade compression.
287 <p>
288
289<font color="Blue"><dt> z_off_t <a name="gzseek">gzseek</a> (gzFile file, z_off_t offset, int whence);</font>
290<dd>
291 Sets the starting position for the next <a href="#gzread">gzread</a> or <a href="#gzwrite">gzwrite</a> on the
292 given compressed file. The offset represents a number of bytes in the
293 uncompressed data stream. The whence parameter is defined as in lseek(2);
294 the value SEEK_END is not supported.
295 <p>
296 If the file is opened for reading, this function is emulated but can be
297 extremely slow. If the file is opened for writing, only forward seeks are
298 supported ; <a href="#gzseek">gzseek</a> then compresses a sequence of zeroes up to the new
299 starting position.
300 <p>
301 <a href="#gzseek">gzseek</a> returns the resulting offset location as measured in bytes from
302 the beginning of the uncompressed stream, or -1 in case of error, in
303 particular if the file is opened for writing and the new starting position
304 would be before the current position.
305 <p>
306
307<font color="Blue"><dt> int <a name="gzrewind">gzrewind</a> (gzFile file);</font>
308<dd>
309 Rewinds the given file. This function is supported only for reading.
310 <p>
311 <a href="#gzrewind">gzrewind</a>(file) is equivalent to (int)<a href="#gzseek">gzseek</a>(file, 0L, SEEK_SET)
312 <p>
313
314<font color="Blue"><dt> z_off_t <a name="gztell">gztell</a> (gzFile file);</font>
315<dd>
316 Returns the starting position for the next <a href="#gzread">gzread</a> or <a href="#gzwrite">gzwrite</a> on the
317 given compressed file. This position represents a number of bytes in the
318 uncompressed data stream.
319 <p>
320
321 <a href="#gztell">gztell</a>(file) is equivalent to <a href="#gzseek">gzseek</a>(file, 0L, SEEK_CUR)
322 <p>
323
324<font color="Blue"><dt> int <a name="gzeof">gzeof</a> (gzFile file);</font>
325<dd>
326 Returns 1 when EOF has previously been detected reading the given
327 input stream, otherwise zero.
328 <p>
329
330<font color="Blue"><dt> int <a name="gzclose">gzclose</a> (gzFile file);</font>
331<dd>
332 Flushes all pending output if necessary, closes the compressed file
333 and deallocates all the (de)compression <a href="#state">state</a>. The return value is the zlib
334 error number (see function <a href="#gzerror">gzerror</a> below).
335 <p>
336
337<font color="Blue"><dt> const char * <a name="gzerror">gzerror</a> (gzFile file, int *errnum);</font>
338<dd>
339 Returns the error message for the last error which occurred on the
340 given compressed file. errnum is set to zlib error number. If an
341 error occurred in the file system and not in the compression library,
342 errnum is set to <a href="#Z_ERRNO">Z_ERRNO</a> and the application may consult errno
343 to get the exact error code.

393<font color="Blue"><dt> int <a name="deflate">deflate</a> (<a href="#z_streamp">z_streamp</a> strm, int flush);</font>
394<dd>
395 <a href="#deflate">deflate</a> compresses as much data as possible, and stops when the input
396 buffer becomes empty or the output buffer becomes full. It may introduce some
397 output latency (reading input without producing any output) except when
398 forced to flush.<p>
399
400 The detailed semantics are as follows. <a href="#deflate">deflate</a> performs one or both of the
401 following actions:
402
403 <ul>
404 <li> Compress more input starting at <a href="#next_in">next_in</a> and update <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a>
405 accordingly. If not all input can be processed (because there is not
406 enough room in the output buffer), <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a> are updated and
407 processing will resume at this point for the next call of <a href="#deflate">deflate</a>().
408
409 <li>
410 Provide more output starting at <a href="#next_out">next_out</a> and update <a href="#next_out">next_out</a> and <a href="#avail_out">avail_out</a>
411 accordingly. This action is forced if the parameter flush is non zero.
412 Forcing flush frequently degrades the compression ratio, so this parameter
413 should be set only when necessary (in interactive applications).
414 Some output may be provided even if flush is not set.
415 </ul> <p>
416
417 Before the call of <a href="#deflate">deflate</a>(), the application should ensure that at least
418 one of the actions is possible, by providing more input and/or consuming
419 more output, and updating <a href="#avail_in">avail_in</a> or <a href="#avail_out">avail_out</a> accordingly ; <a href="#avail_out">avail_out</a>
420 should never be zero before the call. The application can consume the
421 compressed output when it wants, for example when the output buffer is full
422 (<a href="#avail_out">avail_out</a> == 0), or after each call of <a href="#deflate">deflate</a>(). If <a href="#deflate">deflate</a> returns <a href="#Z_OK">Z_OK</a>
423 and with zero <a href="#avail_out">avail_out</a>, it must be called again after making room in the
424 output buffer because there might be more output pending.
425 <p>
426
427 If the parameter flush is set to <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>, all pending output is
428 flushed to the output buffer and the output is aligned on a byte boundary, so
429 that the decompressor can get all input data available so far. (In particular
430 <a href="#avail_in">avail_in</a> is zero after the call if enough output space has been provided
431 before the call.) Flushing may degrade compression for some compression
432 algorithms and so it should be used only when necessary.
433 <p>
434
435 If flush is set to <a href="#Z_FULL_FLUSH">Z_FULL_FLUSH</a>, all output is flushed as with
436 <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>, and the compression <a href="#state">state</a> is reset so that decompression can
437 restart from this point if previous compressed data has been damaged or if
438 random access is desired. Using <a href="#Z_FULL_FLUSH">Z_FULL_FLUSH</a> too often can seriously degrade
439 the compression.
440 <p>
441
442 If <a href="#deflate">deflate</a> returns with <a href="#avail_out">avail_out</a> == 0, this function must be called again
443 with the same value of the flush parameter and more output space (updated
444 <a href="#avail_out">avail_out</a>), until the flush is complete (<a href="#deflate">deflate</a> returns with non-zero
445 <a href="#avail_out">avail_out</a>).
446 <p>
447
448 If the parameter flush is set to <a href="#Z_FINISH">Z_FINISH</a>, pending input is processed,
449 pending output is flushed and <a href="#deflate">deflate</a> returns with <a href="#Z_STREAM_END">Z_STREAM_END</a> if there
450 was enough output space ; if <a href="#deflate">deflate</a> returns with <a href="#Z_OK">Z_OK</a>, this function must be
451 called again with <a href="#Z_FINISH">Z_FINISH</a> and more output space (updated <a href="#avail_out">avail_out</a>) but no
452 more input data, until it returns with <a href="#Z_STREAM_END">Z_STREAM_END</a> or an error. After
453 <a href="#deflate">deflate</a> has returned <a href="#Z_STREAM_END">Z_STREAM_END</a>, the only possible operations on the
454 stream are <a href="#deflateReset">deflateReset</a> or <a href="#deflateEnd">deflateEnd</a>.
455 <p>
456
457 <a href="#Z_FINISH">Z_FINISH</a> can be used immediately after <a href="#deflateInit">deflateInit</a> if all the compression
458 is to be done in a single step. In this case, <a href="#avail_out">avail_out</a> must be at least
459 0.1% larger than <a href="#avail_in">avail_in</a> plus 12 bytes. If <a href="#deflate">deflate</a> does not return
460 <a href="#Z_STREAM_END">Z_STREAM_END</a>, then it must be called again as described above.
461 <p>
462
463 <a href="#deflate">deflate</a>() sets strm-&gt <a href="#adler">adler</a> to the <a href="#adler32">adler32</a> checksum of all input read
464 so far (that is, <a href="#total_in">total_in</a> bytes).
465 <p>
466
467 <a href="#deflate">deflate</a>() may update <a href="#data_type">data_type</a> if it can make a good guess about
468 the input data type (<a href="#Z_ASCII">Z_ASCII</a> or <a href="#Z_BINARY">Z_BINARY</a>). In doubt, the data is considered
469 binary. This field is only for information purposes and does not affect
470 the compression algorithm in any manner.
471 <p>
472
473 <a href="#deflate">deflate</a>() returns <a href="#Z_OK">Z_OK</a> if some progress has been made (more input
474 processed or more output produced), <a href="#Z_STREAM_END">Z_STREAM_END</a> if all input has been
475 consumed and all output has been produced (only when flush is set to
476 <a href="#Z_FINISH">Z_FINISH</a>), <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the stream <a href="#state">state</a> was inconsistent (for example
477 if <a href="#next_in">next_in</a> or <a href="#next_out">next_out</a> was NULL), <a href="#Z_BUF_ERROR">Z_BUF_ERROR</a> if no progress is possible

499 the caller. If <a href="#next_in">next_in</a> is not <a href="#Z_NULL">Z_NULL</a> and <a href="#avail_in">avail_in</a> is large enough (the exact
500 value depends on the compression method), <a href="#inflateInit">inflateInit</a> determines the
501 compression method from the zlib header and allocates all data structures
502 accordingly ; otherwise the allocation will be deferred to the first call of
503 <a href="#inflate">inflate</a>. If <a href="#zalloc">zalloc</a> and <a href="#zfree">zfree</a> are set to <a href="#Z_NULL">Z_NULL</a>, <a href="#inflateInit">inflateInit</a> updates them to
504 use default allocation functions.

509 version assumed by the caller. <a href="#msg">msg</a> is set to null if there is no error
510 message. <a href="#inflateInit">inflateInit</a> does not perform any decompression apart from reading
511 the zlib header if present: this will be done by <a href="#inflate">inflate</a>(). (So <a href="#next_in">next_in</a> and
512 <a href="#avail_in">avail_in</a> may be modified, but <a href="#next_out">next_out</a> and <a href="#avail_out">avail_out</a> are unchanged.)

516<dd>
517 <a href="#inflate">inflate</a> decompresses as much data as possible, and stops when the input
518 buffer becomes empty or the output buffer becomes full. It may some
519 introduce some output latency (reading input without producing any output)
520 except when forced to flush.
521 <p>
522
523 The detailed semantics are as follows. <a href="#inflate">inflate</a> performs one or both of the
524 following actions:
525
526 <ul>
527 <li> Decompress more input starting at <a href="#next_in">next_in</a> and update <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a>
528 accordingly. If not all input can be processed (because there is not
529 enough room in the output buffer), <a href="#next_in">next_in</a> is updated and processing
530 will resume at this point for the next call of <a href="#inflate">inflate</a>().
531
532 <li> Provide more output starting at <a href="#next_out">next_out</a> and update <a href="#next_out">next_out</a> and
533 <a href="#avail_out">avail_out</a> accordingly. <a href="#inflate">inflate</a>() provides as much output as possible,
534 until there is no more input data or no more space in the output buffer
535 (see below about the flush parameter).
536 </ul> <p>
537
538 Before the call of <a href="#inflate">inflate</a>(), the application should ensure that at least
539 one of the actions is possible, by providing more input and/or consuming
540 more output, and updating the next_* and avail_* values accordingly.
541 The application can consume the uncompressed output when it wants, for
542 example when the output buffer is full (<a href="#avail_out">avail_out</a> == 0), or after each
543 call of <a href="#inflate">inflate</a>(). If <a href="#inflate">inflate</a> returns <a href="#Z_OK">Z_OK</a> and with zero <a href="#avail_out">avail_out</a>, it
544 must be called again after making room in the output buffer because there
545 might be more output pending.
546 <p>
547
548 If the parameter flush is set to <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>, <a href="#inflate">inflate</a> flushes as much
549 output as possible to the output buffer. The flushing behavior of <a href="#inflate">inflate</a> is
550 not specified for values of the flush parameter other than <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>
551 and <a href="#Z_FINISH">Z_FINISH</a>, but the current implementation actually flushes as much output
552 as possible anyway.
553 <p>
554
555 <a href="#inflate">inflate</a>() should normally be called until it returns <a href="#Z_STREAM_END">Z_STREAM_END</a> or an
556 error. However if all decompression is to be performed in a single step
557 (a single call of <a href="#inflate">inflate</a>), the parameter flush should be set to
558 <a href="#Z_FINISH">Z_FINISH</a>. In this case all pending input is processed and all pending
559 output is flushed ; <a href="#avail_out">avail_out</a> must be large enough to hold all the
560 uncompressed data. (The size of the uncompressed data may have been saved
561 by the compressor for this purpose.) The next operation on this stream must
562 be <a href="#inflateEnd">inflateEnd</a> to deallocate the decompression <a href="#state">state</a>. The use of <a href="#Z_FINISH">Z_FINISH</a>
563 is never required, but can be used to inform <a href="#inflate">inflate</a> that a faster routine
564 may be used for the single <a href="#inflate">inflate</a>() call.
565 <p>
566
567 If a preset dictionary is needed at this point (see <a href="#inflateSetDictionary">inflateSetDictionary</a>
568 below), <a href="#inflate">inflate</a> sets strm-<a href="#adler">adler</a> to the <a href="#adler32">adler32</a> checksum of the
569 dictionary chosen by the compressor and returns <a href="#Z_NEED_DICT">Z_NEED_DICT</a> ; otherwise
570 it sets strm-&gt <a href="#adler">adler</a> to the <a href="#adler32">adler32</a> checksum of all output produced
571 so far (that is, <a href="#total_out">total_out</a> bytes) and returns <a href="#Z_OK">Z_OK</a>, <a href="#Z_STREAM_END">Z_STREAM_END</a> or
572 an error code as described below. At the end of the stream, <a href="#inflate">inflate</a>()
573 checks that its computed <a href="#adler32">adler32</a> checksum is equal to that saved by the
574 compressor and returns <a href="#Z_STREAM_END">Z_STREAM_END</a> only if the checksum is correct.
575 <p>
576
577 <a href="#inflate">inflate</a>() returns <a href="#Z_OK">Z_OK</a> if some progress has been made (more input processed
578 or more output produced), <a href="#Z_STREAM_END">Z_STREAM_END</a> if the end of the compressed data has
579 been reached and all uncompressed output has been produced, <a href="#Z_NEED_DICT">Z_NEED_DICT</a> if a
580 preset dictionary is needed at this point, <a href="#Z_DATA_ERROR">Z_DATA_ERROR</a> if the input data was
581 corrupted (input stream not conforming to the zlib format or incorrect
582 <a href="#adler32">adler32</a> checksum), <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the stream structure was inconsistent
583 (for example if <a href="#next_in">next_in</a> or <a href="#next_out">next_out</a> was NULL), <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not
584 enough memory, <a href="#Z_BUF_ERROR">Z_BUF_ERROR</a> if no progress is possible or if there was not
585 enough room in the output buffer when <a href="#Z_FINISH">Z_FINISH</a> is used. In the <a href="#Z_DATA_ERROR">Z_DATA_ERROR</a>
586 case, the application may then call <a href="#inflateSync">inflateSync</a> to look for a good
587 compression block.

620
621<dd> This is another version of <a href="#deflateInit">deflateInit</a> with more compression options. The
622 fields <a href="#next_in">next_in</a>, <a href="#zalloc">zalloc</a>, <a href="#zfree">zfree</a> and <a href="#opaque">opaque</a> must be initialized before by
623 the caller.<p>
624
625 The method parameter is the compression method. It must be <a href="#Z_DEFLATED">Z_DEFLATED</a> in
626 this version of the library.<p>
627
628 The windowBits parameter is the base two logarithm of the window size
629 (the size of the history buffer). It should be in the range 8..15 for this
630 version of the library. Larger values of this parameter result in better
631 compression at the expense of memory usage. The default value is 15 if
632 <a href="#deflateInit">deflateInit</a> is used instead.<p>
633
634 The memLevel parameter specifies how much memory should be allocated
635 for the internal compression <a href="#state">state</a>. memLevel=1 uses minimum memory but
636 is slow and reduces compression ratio ; memLevel=9 uses maximum memory
637 for optimal speed. The default value is 8. See zconf.h for total memory
638 usage as a function of windowBits and memLevel.<p>
639
640 The strategy parameter is used to tune the compression algorithm. Use the
641 value <a href="#Z_DEFAULT_STRATEGY">Z_DEFAULT_STRATEGY</a> for normal data, <a href="#Z_FILTERED">Z_FILTERED</a> for data produced by a
642 filter (or predictor), or <a href="#Z_HUFFMAN_ONLY">Z_HUFFMAN_ONLY</a> to force Huffman encoding only (no
643 string match). Filtered data consists mostly of small values with a
644 somewhat random distribution. In this case, the compression algorithm is
645 tuned to <a href="#compress">compress</a> them better. The effect of <a href="#Z_FILTERED">Z_FILTERED</a> is to force more
646 Huffman coding and less string matching ; it is somewhat intermediate
647 between Z_DEFAULT and <a href="#Z_HUFFMAN_ONLY">Z_HUFFMAN_ONLY</a>. The strategy parameter only affects
648 the compression ratio but not the correctness of the compressed output even
649 if it is not set appropriately.<p>
650
651 <a href="#deflateInit2">deflateInit2</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not enough
652 memory, <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if a parameter is invalid (such as an invalid
653 method). <a href="#msg">msg</a> is set to null if there is no error message. <a href="#deflateInit2">deflateInit2</a> does
654 not perform any compression: this will be done by <a href="#deflate">deflate</a>().<p>
655
656<font color="Blue"><dt> int <a name="deflateSetDictionary">deflateSetDictionary</a> (<a href="#z_streamp">z_streamp</a> strm, const Bytef *dictionary, uInt dictLength);</font>
657<dd>
658 Initializes the compression dictionary from the given byte sequence
659 without producing any compressed output. This function must be called
660 immediately after <a href="#deflateInit">deflateInit</a>, <a href="#deflateInit2">deflateInit2</a> or <a href="#deflateReset">deflateReset</a>, before any
661 call of <a href="#deflate">deflate</a>. The compressor and decompressor must use exactly the same
662 dictionary (see <a href="#inflateSetDictionary">inflateSetDictionary</a>).<p>
663
664 The dictionary should consist of strings (byte sequences) that are likely
665 to be encountered later in the data to be compressed, with the most commonly
666 used strings preferably put towards the end of the dictionary. Using a
667 dictionary is most useful when the data to be compressed is short and can be
668 predicted with good accuracy ; the data can then be compressed better than
669 with the default empty dictionary.<p>
670
671 Depending on the size of the compression data structures selected by
672 <a href="#deflateInit">deflateInit</a> or <a href="#deflateInit2">deflateInit2</a>, a part of the dictionary may in effect be
673 discarded, for example if the dictionary is larger than the window size in
674 <a href="#deflate">deflate</a> or deflate2. Thus the strings most likely to be useful should be
675 put at the end of the dictionary, not at the front.<p>
676
677 Upon return of this function, strm-&gt <a href="#adler">adler</a> is set to the Adler32 value
678 of the dictionary ; the decompressor may later use this value to determine
679 which dictionary has been used by the compressor. (The Adler32 value
680 applies to the whole dictionary even if only a subset of the dictionary is
681 actually used by the compressor.)<p>
682
683 <a href="#deflateSetDictionary">deflateSetDictionary</a> returns <a href="#Z_OK">Z_OK</a> if success, or <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if a
684 parameter is invalid (such as NULL dictionary) or the stream <a href="#state">state</a> is
685 inconsistent (for example if <a href="#deflate">deflate</a> has already been called for this stream
686 or if the compression method is bsort). <a href="#deflateSetDictionary">deflateSetDictionary</a> does not
687 perform any compression: this will be done by <a href="#deflate">deflate</a>().<p>

690<dd>
691 Sets the destination stream as a complete copy of the source stream.<p>
692
693 This function can be useful when several compression strategies will be
694 tried, for example when there are several ways of pre-processing the input
695 data with a filter. The streams that will be discarded should then be freed
696 by calling <a href="#deflateEnd">deflateEnd</a>. Note that <a href="#deflateCopy">deflateCopy</a> duplicates the internal
697 compression <a href="#state">state</a> which can be quite large, so this strategy is slow and
698 can consume lots of memory.<p>

702 (such as <a href="#zalloc">zalloc</a> being NULL). <a href="#msg">msg</a> is left unchanged in both source and

707 but does not free and reallocate all the internal compression <a href="#state">state</a>.
708 The stream will keep the same compression level and any other attributes
709 that may have been set by <a href="#deflateInit2">deflateInit2</a>.<p>
710
711 <a href="#deflateReset">deflateReset</a> returns <a href="#Z_OK">Z_OK</a> if success, or <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the source
712 stream <a href="#state">state</a> was inconsistent (such as <a href="#zalloc">zalloc</a> or <a href="#state">state</a> being NULL).<p>

715<dd>
716 Dynamically update the compression level and compression strategy. The
717 interpretation of level and strategy is as in <a href="#deflateInit2">deflateInit2</a>. This can be
718 used to switch between compression and straight copy of the input data, or
719 to switch to a different kind of input data requiring a different
720 strategy. If the compression level is changed, the input available so far
721 is compressed with the old level (and may be flushed); the new level will
722 take effect only at the next call of <a href="#deflate">deflate</a>().<p>
723
724 Before the call of <a href="#deflateParams">deflateParams</a>, the stream <a href="#state">state</a> must be set as for
725 a call of <a href="#deflate">deflate</a>(), since the currently available input may have to
726 be compressed and flushed. In particular, strm-&gt <a href="#avail_out">avail_out</a> must be
727 non-zero.<p>
728
729 <a href="#deflateParams">deflateParams</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the source

739 The windowBits parameter is the base two logarithm of the maximum window
740 size (the size of the history buffer). It should be in the range 8..15 for
741 this version of the library. The default value is 15 if <a href="#inflateInit">inflateInit</a> is used
742 instead. If a compressed stream with a larger window size is given as
743 input, <a href="#inflate">inflate</a>() will return with the error code <a href="#Z_DATA_ERROR">Z_DATA_ERROR</a> instead of
744 trying to allocate a larger window.<p>
745
746 <a href="#inflateInit2">inflateInit2</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not enough
747 memory, <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if a parameter is invalid (such as a negative
748 memLevel). <a href="#msg">msg</a> is set to null if there is no error message. <a href="#inflateInit2">inflateInit2</a>
749 does not perform any decompression apart from reading the zlib header if
750 present: this will be done by <a href="#inflate">inflate</a>(). (So <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a> may be
751 modified, but <a href="#next_out">next_out</a> and <a href="#avail_out">avail_out</a> are unchanged.)<p>

754<dd>
755 Initializes the decompression dictionary from the given uncompressed byte
756 sequence. This function must be called immediately after a call of <a href="#inflate">inflate</a>
757 if this call returned <a href="#Z_NEED_DICT">Z_NEED_DICT</a>. The dictionary chosen by the compressor
758 can be determined from the Adler32 value returned by this call of
759 <a href="#inflate">inflate</a>. The compressor and decompressor must use exactly the same
760 dictionary (see <a href="#deflateSetDictionary">deflateSetDictionary</a>).<p>
761
762 <a href="#inflateSetDictionary">inflateSetDictionary</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if a
763 parameter is invalid (such as NULL dictionary) or the stream <a href="#state">state</a> is
764 inconsistent, <a href="#Z_DATA_ERROR">Z_DATA_ERROR</a> if the given dictionary doesn't match the
765 expected one (incorrect Adler32 value). <a href="#inflateSetDictionary">inflateSetDictionary</a> does not
766 perform any decompression: this will be done by subsequent calls of
767 <a href="#inflate">inflate</a>().<p>

772 description of <a href="#deflate">deflate</a> with <a href="#Z_FULL_FLUSH">Z_FULL_FLUSH</a>) can be found, or until all

774

777 or <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the stream structure was inconsistent. In the success
778 case, the application may save the current current value of <a href="#total_in">total_in</a> which
779 indicates where valid compressed data was found. In the error case, the
780 application may repeatedly call <a href="#inflateSync">inflateSync</a>, providing more input each time,

785 This function is equivalent to <a href="#inflateEnd">inflateEnd</a> followed by <a href="#inflateInit">inflateInit</a>,
786 but does not free and reallocate all the internal decompression <a href="#state">state</a>.
787 The stream will keep attributes that may have been set by <a href="#inflateInit2">inflateInit2</a>.
788 <p>
789

797 These functions are not related to compression but are exported
798 anyway because they might be useful in applications using the
799 compression library.
800<h3> Function list </h3>
801<ul>
802<li> uLong <a href="#adler32">adler32</a> (uLong <a href="#adler">adler</a>, const Bytef *buf, uInt len);
803<li> uLong <a href="#crc32">crc32</a> (uLong crc, const Bytef *buf, uInt len);
804</ul>
805<h3> Function description </h3>
806<dl>
807<font color="Blue"><dt> uLong <a name="adler32">adler32</a> (uLong <a href="#adler">adler</a>, const Bytef *buf, uInt len);</font>
808<dd>
809 Update a running Adler-32 checksum with the bytes buf[0..len-1] and
810 return the updated checksum. If buf is NULL, this function returns
811 the required initial value for the checksum.
812 <p>
813 An Adler-32 checksum is almost as reliable as a CRC32 but can be computed
814 much faster. Usage example:
815 <pre>
816
817 uLong <a href="#adler">adler</a> = <a href="#adler32">adler32</a>(0L, <a href="#Z_NULL">Z_NULL</a>, 0);
818
819 while (read_buffer(buffer, length) != EOF) {
820 <a href="#adler">adler</a> = <a href="#adler32">adler32</a>(<a href="#adler">adler</a>, buffer, length);
821 }
822 if (<a href="#adler">adler</a> != original_adler) error();
823 </pre>
824
825<font color="Blue"><dt> uLong <a name="crc32">crc32</a> (uLong crc, const Bytef *buf, uInt len);</font>
826<dd>
827 Update a running crc with the bytes buf[0..len-1] and return the updated
828 crc. If buf is NULL, this function returns the required initial value
829 for the crc. Pre- and post-conditioning (one's complement) is performed
830 within this function so it shouldn't be done by the application.
831 Usage example:
832 <pre>
833
834 uLong crc = <a href="#crc32">crc32</a>(0L, <a href="#Z_NULL">Z_NULL</a>, 0);
835
836 while (read_buffer(buffer, length) != EOF) {
837 crc = <a href="#crc32">crc32</a>(crc, buffer, length);
838 }
839 if (crc != original_crc) error();

871 The application must update <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a> when <a href="#avail_in">avail_in</a> has
872 dropped to zero. It must update <a href="#next_out">next_out</a> and <a href="#avail_out">avail_out</a> when <a href="#avail_out">avail_out</a>
873 has dropped to zero. The application must initialize <a href="#zalloc">zalloc</a>, <a href="#zfree">zfree</a> and
874 <a href="#opaque">opaque</a> before calling the init function. All other fields are set by the
875 compression library and must not be updated by the application. <p>
876
877 The <a href="#opaque">opaque</a> value provided by the application will be passed as the first
878 parameter for calls of <a href="#zalloc">zalloc</a> and <a href="#zfree">zfree</a>. This can be useful for custom
879 memory management. The compression library attaches no meaning to the
880 <a href="#opaque">opaque</a> value. <p>
881
882 <a href="#zalloc">zalloc</a> must return <a href="#Z_NULL">Z_NULL</a> if there is not enough memory for the object.
883 If zlib is used in a multi-threaded application, <a href="#zalloc">zalloc</a> and <a href="#zfree">zfree</a> must be
884 thread safe. <p>
885
886 On 16-bit systems, the functions <a href="#zalloc">zalloc</a> and <a href="#zfree">zfree</a> must be able to allocate
887 exactly 65536 bytes, but will not be required to allocate more than this
888 if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS,
889 pointers returned by <a href="#zalloc">zalloc</a> for objects of exactly 65536 bytes *must*
890 have their offset normalized to zero. The default allocation function
891 provided by this library ensures this (see zutil.c). To reduce memory
892 requirements and avoid any allocation of 64K objects, at the expense of
893 compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h).
894 <p>
895
896 The fields <a href="#total_in">total_in</a> and <a href="#total_out">total_out</a> can be used for statistics or
897 progress reports. After compression, <a href="#total_in">total_in</a> holds the total size of
898 the uncompressed data and may be saved for use in the decompressor
899 (particularly if the decompressor wants to decompress everything in
900 a single step). <p>
