Member Function Documentation

static int ChecksumData	(	const void *	buffer,
		const int	length
	)			[static]

Performs a simple and quick checksum of a buffer

Parameters:

	buffer	the data buffer to checksum
	the	length of the data buffer in bytes

Returns:

the checksum for the data, the checksum returned is never 0

static void ChecksumDataWithSlots	(	int *	checksumSlots,
		const int	numSlots,
		const void *	buffer,
		const int	length
	)			[static]

Performs a simple and quick checksum of a buffer using a certain chunk size to generate more than 32 bits of data.

Parameters:

	checksumSlots	The checksum slots array, this is cumulative so make sure the array is initialise to a known state.
	numSlots	The number of checksumSlots supplied in the array.
	buffer	the data buffer to checksum.
	the	length of the data buffer in bytes. When using the cumulative feature of this function the number of bytes must be a multiple of numSlots except for the last use of this function for a particular block of data.
