INSTALL ZLIB INSTALL

The library does not install any signal handler. The gzip format was designed for single-ДЇile compression on file systems, has a larger header than zlib to maintainДirectory information, and uses a different, slower check method than zlib. The zlib format was designed to be compact and fast for use in memoryДЄnd on communications channels. This library can optionally read and write gzip and raw deflate streams in Gzip wrapper, documented in RFC 1952, wrapped around a deflate stream. The gzip format is different from the zlib format. With an interface similar to that of stdio using the functions that start The library also supports reading and writing files in gzip (.gz) format The zlib format, which is a zlib wrapper documented in RFC 1950, wrappedДЄround a deflate stream, which is itself documented in RFC 1951. The compressed data format used by default by the in-memory functions is (providing more output space) before each call. In the latter case, theДЄpplication must provide more input and/or consume the output Repeated calls of the compression function.
