* ZLIB.INC - Interface to the general purpose compression library
|
|
*
|
|
* ILE RPG400 version by Patrick Monnerat, DATASPHERE.
|
|
* Version 1.2.1
|
|
*
|
|
*
|
|
* WARNING:
|
|
* Procedures inflateInit(), inflateInit2(), deflateInit(),
|
|
* deflateInit2() and inflateBackInit() need to be called with
|
|
* two additional arguments:
|
|
* the package version string and the stream control structure.
|
|
* size. This is needed because RPG lacks some macro feature.
|
|
* Call these procedures as:
|
|
* inflateInit(...: ZLIB_VERSION: %size(z_stream))
