* ZLIB.INC - Interface to the general purpose compression library |
|
* |
|
* ILE RPG400 version by Patrick Monnerat, DATASPHERE. |
|
* Version 1.2.11 |
|
* |
|
* |
|
* 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)) |
|
