/brief calculate a crc32 from a data block
/param crcContext pointer to context variable /param inBuf input buffer to checksum /param inLen length of input buffer /param crc32 pointer to Uint32 to store the final CRC into
/returns 0 for OK, -1 on error
int SDLTest_Crc32Done | ( | SDLTest_Crc32Context * | crcContext ) |
/brief clean up CRC context
/param crcContext pointer to context variable
/returns 0 for OK, -1 on error
int SDLTest_Crc32Init | ( | SDLTest_Crc32Context * | crcContext ) |
/brief Initialize the CRC context
Note: The function initializes the crc table required for all crc calculations.
/param crcContext pointer to context variable
/returns 0 for OK, -1 on error
