cannam@89 1 * ZLIB.INC - Interface to the general purpose compression library
cannam@89 2 *
cannam@89 3 * ILE RPG400 version by Patrick Monnerat, DATASPHERE.
cannam@89 4 * Version 1.2.7
cannam@89 5 *
cannam@89 6 *
cannam@89 7 * WARNING:
cannam@89 8 * Procedures inflateInit(), inflateInit2(), deflateInit(),
cannam@89 9 * deflateInit2() and inflateBackInit() need to be called with
cannam@89 10 * two additional arguments:
cannam@89 11 * the package version string and the stream control structure.
cannam@89 12 * size. This is needed because RPG lacks some macro feature.
cannam@89 13 * Call these procedures as:
cannam@89 14 * inflateInit(...: ZLIB_VERSION: %size(z_stream))
