Function Documentation

int ccInflateCCZFile	(	const char *	filename,
		unsigned char **	out
	)

inflates a CCZ file into memory

Returns:

the length of the deflated buffer

Since:

v0.99.5

int ccInflateGZipFile	(	const char *	filename,
		unsigned char **	out
	)

inflates a GZip file into memory

Returns:

the length of the deflated buffer

Since:

v0.99.5

int ccInflateMemory	(	unsigned char *	in,
		unsigned int	inLength,
		unsigned char **	out
	)

Inflates either zlib or gzip deflated memory. The inflated memory is expected to be freed by the caller.

It will allocate 256k for the destination buffer. If it is not enough it will multiply the previous buffer size per 2, until there is enough memory.

Returns:

the length of the deflated buffer

Since:

v0.8.1

int ccInflateMemoryWithHint	(	unsigned char *	in,
		unsigned int	inLength,
		unsigned char **	out,
		unsigned int	outlengthHint
	)

Inflates either zlib or gzip deflated memory. The inflated memory is expected to be freed by the caller.

outlengthHint is assumed to be the needed room to allocate the inflated buffer.

Returns:

the length of the deflated buffer

Since:

v1.0.0
