* ZLIB.INC - Interface to the general purpose compression library | |
* | |
* ILE RPG400 version by Patrick Monnerat, DATASPHERE. | |
* Version 1.2.3.9 | |
* | |
* | |
* 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)) | |
