NAME

	UMult64 -- unsigned 32 by 32 bit multiply with 64 bit result. (V39)

SYNOPSIS

	result = UMult64(arg1,arg2);
	D0:D1               D0   D1
	ULONG UMult64(ULONG,ULONG);

FUNCTION

	Returns the unsigned 64 bit result of multiplying arg1 by arg2.

INPUTS

	arg1, arg2 - numbers to multiply

RESULT

	result - the unsigned 64 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
