prod=_mul(val1, val2);
val1 and val2 are both 8-bit, 16-bit, or 48-bit integers
* or less
** large numbers will overflow with wrong results
Performs an optimized multiplication. By accepting a different type than it returns,
this function avoids the overhead of converting the parameters to a larger type.

The function can take variable parameters. The user can use stdarg library to
create functions that take variable parameters.
Function dependent.
The stdarg library allows the user to create functions that supports variable
arguments.
The function that will accept a variable number of arguments must have at least
one actual, known parameters, and it may have more. The number of arguments
is often passed to the function in one of its actual parameters. If the variable-
length argument list can involve more that one type, the type information is
generally passed as well. Before processing can begin, the function creates a
special argument pointer of type va_list.
