|

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))
|
---|
15 | *
|
---|
16 | /if not defined(ZLIB_H_)
