                     wide *target);
multiplicand
The number to be multiplied by the multiplier.
multiplier

The number by which the multiplicand is to be multiplied.
target
A pointer to the location where the product of the two numbers is to be stored.

function result
A pointer to the target value, which holds the result.

DESCRIPTION
The operation has a bias of 0 bits. The bias of the result is the sum of the biases of the inputs.
