encoding_crc32()

uint32_t encoding_crc32	(	uint32_t	crc,
		const uint8_t *	buf,
		size_t	len
	)

Here is the caller graph for this function:

file_crc32()

uint32_t file_crc32	(	uint32_t	crc,
		const char *	path
	)

Calculate a CRC32 from the first part of the given file. "first part" being the first (CRC32_BUFFER_SIZE * CRC32_MAX_MB) bytes.

Returns: the crc32, or 0 if there was an error.
