MAC_BN_I

Multiplies two integer big numbers and accumulates the result with the third integer big number.

Syntax

IppStatus ippsMAC_BN_I(IppsBigNumState*
pA
, IppsBigNumState*
pB
, IppsBigNumState*
pR
);
Include Files
ippcp.h
Parameters
pA
Pointer to the multiplicand of
IppsBigNumState
.
pB
Pointer to the multiplier of
IppsBigNumState
.
pR
Pointer to the multiplication result.
Description
The function multiplies one integer big number by another and accumulates the result with the third input integer big number regardless of their signs and sizes. The function subsequently returns the result of the operation.
The following pseudocode represents this function:
pR
pR
+
pA
*
pB
.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr
Indicates an error condition if any of the specified pointers is
NULL
.
ippStsOutOfRangeErr
Indicates an error condition if
IppsBigNumState *
pR
is smaller than the result data length.
ippStsContextMatchErr
Indicates an error condition if any of the context parameters does not match the operation.
The function executes only under the condition that the size
IppsBigNumState *
pR
is not less than the sum of the lengths of
IppsBigNumState *
pA
or that of
IppsBigNumState *
pB
minus one.
