SdlCrc32

Calculate a CRC-32 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-32 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: Cardinal : The current checksum for this data set, or 0 for a new data set.

AData: Pointer

ASize: NativeInt

Returns

Cardinal: A CRC-32 checksum value of all blocks in the data set.
