Functions
int32	gg_deflateInit (z_streamp strm, int32 level)
	Wrapper to zlib deflateInit() which sets strm to uses MemAlloc() / MemFree().
int32	gg_inflateInit (z_streamp strm)
	Wrapper to zlib inflateInit() which sets strm to uses MemAlloc() / MemFree().
int32	gg_deflate (z_streamp strm, uint8 *dest, uint32 *pDestLen, const uint8 *source, uint32 sourceLen)
	Wrapper to zlib deflate() which first resets strm. Expects dest to be big enough to hold compressed data, and returns Z_BUF_ERROR if it is not. More...
int32	gg_compress (uint8 *dest, uint32 *pDestLen, const uint8 *source, uint32 sourceLen)
	As zlib compress() but uses MemAlloc() / MemFree().
int32	gg_compress2 (uint8 *dest, uint32 *pDestLen, const uint8 *source, uint32 sourceLen, int32 level)
	As zlib compress2() but uses MemAlloc() / MemFree().
int32	gg_uncompress (uint8 *dest, uint32 *pDestLen, const uint8 *source, uint32 sourceLen)
	As zlib uncompress() but uses MemAlloc() / MemFree().
uint32	gg_compressBound (uint32 sourceLen)
	As zlib compressBound() but takes/returns uint32.

Function Documentation

gg_deflate()

int32 gg_deflate	(	z_streamp	strm,
		uint8 *	dest,
		uint32 *	pDestLen,
		const uint8 *	source,
		uint32	sourceLen
	)

Wrapper to zlib deflate() which first resets strm. Expects dest to be big enough to hold compressed data, and returns Z_BUF_ERROR if it is not.

Returns

Z_OK if successful, or one of the zlib errors.
