Function Documentation

compute16CCITT()

uint16_t compute16CCITT	(	const void *	buf,
		size_t	buf_length
	)

This function computes the CRC-8-CCITT (Cyclic Redundancy Check) of a buffer "buf" of "buf_length" bytes.

Note that a void pointer is a pointer that has no associated data type with it. A void pointer can hold address of any type and can be typcasted to any type.

isValid()

bool isValid

(

const void *

block

)

Validates whether the calculated CRC of the SBF block at hand matches the CRC field of the streamed SBF block.

Parameters

block

The SBF block that we are interested in

Returns

True if the CRC check of the SBFBlock has passed, false otherwise
