/**

|
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 signed value Dividend by the 64-bit signed
|
|
value Divisor and generates a 64-bit signed quotient. If Remainder is not
|
|
NULL, then the 64-bit signed remainder is returned in Remainder. This
|
|
function returns the 64-bit signed quotient.
|
|
|
|
It is the caller's responsibility to not call this function with a Divisor of 0.
|
|
If Divisor is 0, then the quotient and remainder should be assumed to be
|
|
the largest negative integer.
|
|
|
|
If Divisor is 0, then ASSERT().
|
|
|
|
@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.
