crc32()

template<uint32_t Poly>

uint32_t crc32	(	const uint8_t *	data,
		uint32_t	crc,
		std::size_t	size
	)

Evaluate the CRC32 of the first size bytes of a data buffer, using a specific polynomium and an initial value.

The crc is accomplished by reversing the input, the initial value and the output (remainder).

Parameters

data	Input data buffer pointer
crc	Initial value of the checksum
size	Number of bytes

Returns

32-bit remainder of the checksum
