Member Function Documentation

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

static void ChecksumDataWithSlots	(	int *	checksumSlots,
		const size_t	numSlots,
		const void *	buffer,
		const size_t	length,
		const bool	initialiseSlots = `false`,
		const bool	initialiseSlotsWithLength = `false`
	)

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. By default this is cumulative so make sure the array is initialised to a known state.
numSlots	The number of checksumSlots supplied in the array.
buffer	The data buffer to checksum.
length	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. By default the checksumSlots are not initialised. Setting this to be true will initialise the checksumSlots. By default the length of the data is not used to seed the checksumSlots when calculating the checksum. If this is true then the length will be used to seed the checksumSlots and this will alter the result of any cumulative checksum.
