* WARNING: |

|
* Procedures inflateInit(), inflateInit2(), deflateInit(), |
|
9
|
* deflateInit2() and inflateBackInit() need to be called with |
|
10
|
* two additional arguments: |
|
11
|
* the package version string and the stream control structure. |
|
12
|
* size. This is needed because RPG lacks some macro feature. |
|
13
|
* Call these procedures as: |
|
14
|
* inflateInit(...: ZLIB_VERSION: %size(z_stream)) |
