Function Documentation

BFChecksumCreate()

int BFChecksumCreate	(	BFChecksumTools *	tools,
		BFChecksumType	type )

Inits checksum context

BFChecksumDestroy()

void BFChecksumDestroy

(

BFChecksumTools *

tools

)

Cleans up memory for tools

Caller doesn't own members but still owns tools struct

BFChecksumFinal()

int BFChecksumFinal

(

BFChecksumTools *

tools

)

finalizes context

BFChecksumGetDigestString()

int BFChecksumGetDigestString	(	BFChecksumTools *	tools,
		char *	dig )

dig: must have length BFChecksumTools.digestLength + 1

BFChecksumGetDigestStringLength()

size_t BFChecksumGetDigestStringLength

(

BFChecksumTools *

tools

)

Returns the suggested string length not including null term character

BFChecksumUpdate()

int BFChecksumUpdate	(	BFChecksumTools *	tools,
		const void *	data,
		size_t	size )

updates context
