Module Name:
DivS64x64Remainder.c
Abstract:
Integer division worker functions for Ia32.
--*/
#include "..\BaseLibInternal.h"
/**
Worker function that Divides a 64-bit signed integer by a 64-bit signed integer and
generates a 64-bit signed result and a optional 64-bit signed remainder.
This function divides the 64-bit unsigned value Dividend by the 64-bit
unsigned value Divisor and generates a 64-bit unsigned quotient. If Remainder
is not NULL, then the 64-bit unsigned remainder is returned in Remainder.
This function returns the 64-bit unsigned quotient.
@param Dividend A 64-bit signed value.
@param Divisor A 64-bit signed value.
@param Remainder A pointer to a 64-bit signed value. This parameter is
optional and may be NULL.
@return Dividend / Divisor
