15 Divides a 64-bit signed integer by a 64-bit signed integer and generates a
16 64-bit signed result and a optional 64-bit signed remainder.
18 This function divides the 64-bit signed value Dividend by the 64-bit signed
19 value Divisor and generates a 64-bit signed quotient. If Remainder is not
20 NULL, then the 64-bit signed remainder is returned in Remainder. This
21 function returns the 64-bit signed quotient.
23 It is the caller's responsibility to not call this function with a Divisor of 0.
24 If Divisor is 0, then the quotient and remainder should be assumed to be
25 the largest negative integer.
27 If Divisor is 0, then ASSERT().
29 @param Dividend A 64-bit signed value.
30 @param Divisor A 64-bit signed value.
31 @param Remainder A pointer to a 64-bit signed value. This parameter is
32 optional and may be NULL.
