Calculate a CRC for a block of data
long PtCRC( const char *buffer,
int nbytes );
ph
This function generates a 32-bit 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
(see the QNX Neutrino Utilities Reference)
to cache images. |
You can call
PtCRCValue()
to calculate a running CRC checksum.
The cyclic redundancy check.
