Function Documentation

crc32()

uint32_t crc32	(	const void *	buf,
		size_t	size
	)

CRC-32 checksum.

Uses the 0xedb88320 polynomial

Note

enable the crc32_fast module for a look-up table based implementation that trades code size for speed.

Parameters

[in]	buf	The data to checksum
[in]	size	Length of the data in bytes

Returns

32 bit sized hash in the interval [0..2^32]
