1 * ZLIB.INC - Interface to the general purpose compression library
2 *
3 * ILE RPG400 version by Patrick Monnerat, DATASPHERE.
4 * Version 1.2.8
5 *
6 *
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))
