SdlCrc16

Calculate a CRC-16 value.

See Cyclic Redundancy Check.

This function can be called multiple times, to stream data to be checksummed in blocks. Each call must provide the previous CRC-16 return value to be updated with the next block. The first call to this function for a set of blocks should pass in a zero CRC value.

Parameters

ACrc: Word : The current checksum for this data set, or 0 for a new data set.

AData: Pointer : A new block of data to add to the checksum.

ASize: NativeInt : The size, in bytes, of the new block of data.

Returns

Word: A CRC-16 checksum value of all blocks in the data set.

Remarks

It is safe to call this function from any thread
