Parameters
- pA
- Pointer to the multiplicand ofIppsBigNumState.
- pB
- Pointer to the multiplier ofIppsBigNumState.
- 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 isNULL.
- ippStsOutOfRangeErr
- Indicates an error condition ifIppsBigNumState *pRis 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.
