| 7 | * 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)) |
