However that causes a static linkage to zlib to bring in many routines that are often not used. All that is required to duplicate the compilation environment of gzprintf() is to include gzguts.h. So that is now done in zutil.c to assure that the correct flags are returned. 2012-01-30T05:15:24+00:00 Mark Adler madler@alumni.caltech.edu 2012-01-30T03:25:44+00:00 urn:sha1:7b3f71ba5fc29f3743fae9b9dbe071018a6b6b4e 2012-01-17T00:44:29+00:00 Mark Adler madler@alumni.caltech.edu 2012-01-16T03:31:31+00:00 urn:sha1:0ddfbd2346cc23ffbcea9a0c491e5da39cf743d2 2011-12-20T06:31:02+00:00 Mark Adler madler@alumni.caltech.edu 2011-12-20T06:31:02+00:00 urn:sha1:b745a48f413e114373f0f26e72411ff415f004d4 Moves new function definitions in order to preserve shared library compatibility with previous versions.

This enables constructing and decompressing a series of concatenated deflate streams where each can depend on the history of uncompressed data that precedes it. This generalizes deflateSetDictionary() and inflateSetDictionary() to permit setting the dictionary in the middle of a stream for raw deflate and inflate. This in combination with the Keep functions enables a scheme for updating files block by block with the transmission of compressed data, where blocks are sent with deflateResetKeep() to retain history for better compression, and deflateSetDictionary() is used for blocks already present at the receiver to skip compression but insert that data in the history, again for better compression. The corresponding inflate calls are done on the receiver side.
