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. 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. 2011-10-08T06:13:37+00:00 Mark Adler madler@alumni.caltech.edu 2011-10-08T06:00:42+00:00 urn:sha1:77b47d55f14be032c0ee10da44bbe7591be0abd8 The Microsoft CAB file format compresses each block with completed deflate streams that depend on the sliding window history of the previous block in order to decode. inflateResetKeep() does what inflateReset() does, except the sliding window history from the previous inflate operation is retained.
