Function Documentation

gp_io_zlib()

gp_io * gp_io_zlib	(	gp_io *	io,
		size_t	comp_size )

Create a Zlib RAW inflate stream on the top of the existing I/O stream.

The stream will read up to comp_size bytes from the parent I/O.

If comp_size is 0, no limit on number bytes from the parent stream is set. However if end of compressed stream is reached the last read will attempt to seek back by the number of extra buffered bytes.

gp_io_zlib_reset()

int gp_io_zlib_reset	(	gp_io *	io,
		gp_io *	sub_io,
		size_t	comp_size )

Repurposes existing Zlib stream for new decompression.

Returns

Zero on success. Returns non-zero on failure and errno is set.
