RSA Security 5 manual Int BGenerateRandomBytes

		B_GenerateRandomBytes
B_GenerateRandomBytes
int B_GenerateRandomBytes (
B_ALGORITHM_OBJ randomAlgorithm,		/* random algorithm */
unsigned char	*output,	/* buffer for output bytes */
unsigned int	outputLen,	/* number of bytes to output */
A_SURRENDER_CTX *surrenderContext		/* surrender context */
);

Description

B_GenerateRandomBytes generates outputLen pseudo-random bytes from randomAlgorithm, storing the result in output. The randomAlgorithm must have been seeded. The surrender context for processing and canceling during lengthy operations is surrenderContext; if its value is (A_SURRENDER_CTX *)NULL_PTR, Crypto-C does not use it. See B_RandomInit.

Return value

Value	Description
0	Operation was successful.
non-zero	see Appendix A, ”Crypto-C Error Types”
