Detailed Description

Include file for SDL test framework.

This code is a part of the SDL2_test library, not the main SDL library.

		CrcUint8 *	inBuf,
		CrcUint32	inLen,
		CrcUint32 *	crc32
	)

/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

)

/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.
