- * ZLIB.INC - Interface to the general purpose compression library

- * ILE RPG400 version by Patrick Monnerat, DATASPHERE.
- * Version 1.2.3
- *
- *
- * 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))
