zlib – compression/decompression library Synopsis [see zlib.h for full description] Description The zlib library is a general purpose data compression library. The code is thread safe, assuming that the standard library functions used are thread safe, such as memory allocation routines. It provides in-memory compression and decompression functions, including integrity checks of the uncompressed data….
