Function Documentation

tmj_zstd_decompress()

uint8_t * tmj_zstd_decompress	(	const uint8_t *	data,
		size_t	data_size,
		size_t *	decompressed_size
	)

Decompresses a zstd-compressed buffer of bytes.

This routine does not use streaming decompression, so the given buffer must have a frame header that includes the content size. See https://github.com/facebook/zstd/blob/dev/doc/zstd_compression_format.md#frame_header for detail.

Parameters

	data	A zstd-compressed buffer of unsigned bytes. The zstd frame header for this buffer must include the content size.
	data_size	The length of the buffer.
[out]	decompressed_size	The length of the returned decompressed buffer.

Returns

On success, returns a dynamically-allocated (and decompressed) buffer of unsigned bytes. The returned buffer must be freed by the caller.

tmj_zlib_decompress()

uint8_t * tmj_zlib_decompress	(	const uint8_t *	data,
		size_t	data_size,
		size_t *	decompressed_size
	)

Decompresses a zlib/gzip-compressed buffer of bytes.

Parameters

	data	A zlib/gzip-compressed buffer of unsigned bytes.
	data_size	The length of the buffer.
[out]	decompressed_size	The length of the returned decompressed buffer.

Returns

On success, returns a dynamically-allocated (and decompressed) buffer of unsigned bytes. The returned buffer must be freed by the caller.

tmj_zlib_compress()

uint8_t * tmj_zlib_compress	(	const uint8_t *	data,
		size_t	data_size,
		int	level,
		size_t *	compressed_size
	)

Compresses a buffer of bytes with zlib.

Parameters

	data	A buffer of unsigned bytes.
	data_size	The length of the buffer.
	level	The desired level of zlib compression (0-9).
[out]	compressed_size	The length of the returned compressed buffer.

Returns

On success, returns a dynamically-allocated, zlib-compressed buffer of unsigned bytes. The returned buffer must be freed by the caller.

tmj_b64_encode()

char * tmj_b64_encode	(	uint8_t *	data,
		size_t	size
	)

Encodes a base64 string.

Parameters

data	An array of unsigned bytes.
size	The length of the array.

Returns

On success, returns a dynamically-allocated null-terminated base64 string. The returned array must be freed by the caller.

tmj_b64_decode()

uint8_t * tmj_b64_decode	(	const char *	data,
		size_t *	decoded_size
	)

Decodes a base64 string.

Parameters

	data	A null-terminated base64 string.
[out]	decoded_size	The length of the returned decoded buffer.

Returns

On success, returns a dynamically-allocated array of unsigned bytes. The returned array must be freed by the caller.
