NAME

	SMult32 -- signed 32 by 32 bit multiply with 32 bit result. (V36)

SYNOPSIS

	result = SMult32(arg1,arg2);
D0 D0 D1
LONG SMult32(LONG,LONG);

FUNCTION

	Returns the signed 32 bit result of multiplying arg1 by arg2.

INPUTS

	arg1, arg2 - numbers to multiply

RESULT

	result - the signed 32 bit result of multiplying arg1 by arg2.

NOTES

	Unlike other Amiga library function calls, the utility.library
32 bit math routines do NOT require A6 to be loaded with a
pointer to the library base. A6 can contain anything the application
wishes. This is in order to avoid overhead in calling them.
In addition, the utility.library math routines preserve all
address registers including A0 and A1
