B_DigestUpdate
B_DigestUpdate
Description
B_DigestUpdate updates
algorithmObject
with
partInLen
bytes from
partIn
. 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.
B_DigestUpdate may be called zero or more times to supply the data by parts.
See
B_DigestInit.
Return value
int B_DigestUpdate (
B_ALGORITHM_OBJ algorithmObject, /* algorithm object */
unsigned char *partIn, /* input data */
unsigned int partInLen, /* length of input data */
A_SURRENDER_CTX *surrenderContext /* surrender context */
);
Value Description
0 Operation was successful.
non-zero see Appendix A, “Crypto-C Error Types”
