Multiplies two integer big numbers.
Syntax
IppStatus ippsMul_BN(IppsBigNumState *a, IppsBigNumState *b, IppsBigNumState * r);
Parameters
a |
Multiplicand of IppsBigNumState. |
b |
Multiplier of IppsBigNumState. |
r |
Multiplication result. |
Description
This function is declared in the ippcp.h file. The function multiplies an integer big number by another integer big number regardless of their signs and sizes and returns the result of the operation.
The following pseudocode represents this function:
r ← a *b.
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 *r is smaller than the result data length. |
Note
The function executes only under the condition that the size IppsBigNumState *r is not less than the sum of the lengths of IppsBigNumState *a or that of IppsBigNumState *b minus one.
