.SH NAME
zlib \- compression/decompression library
.SH SYNOPSIS
The
.I zlib
library is a general purpose data compression library.
-The code is thread safe.
+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.
This version of the library supports only one compression method (deflation)
-but other algorithms will be added later
-and will have the same stream interface.
+but other algorithms may be added later
+with the same stream interface.
.LP
Compression can be done in a single step if the buffers are large enough
-(for example if an input file is mmap'ed),
or can be done by repeated calls of the compression function.
In the latter case,
the application must provide more input and/or consume the output
.LP
The library does not install any signal handler.
The decoder checks the consistency of the compressed data,
-so the library should never crash even in case of corrupted input.
+so the library should never crash even in the case of corrupted input.

All functions of the compression library are documented in the file
.IR zlib.h .

+.I test/example.c
