The

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.

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
