* WARNING: |
| 8 |
* 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)) |
