Calculate a CRC for a block of data
#include <photon/PxProto.h> long PxCRC( const char *buffer, int nbytes );
This function generates a cyclic redundancy check or CRC on the nbytes of data pointed to by buffer.
 |
We recommend that bitmaps and images have a CRC on the image data and the palette. This CRC is used extensively by phrelay to cache images. |
The cyclic redundancy check.
