Subtracts one value of type INT_PTR from another.
NTSTATUS RtlIntPtrSub( _In_ INT_PTR iMinuend, _In_ INT_PTR iSubtrahend, _Out_ INT_PTR *piResult );
- iMinuend [in]
The value from which iSubtrahend is subtracted.
- iSubtrahend [in]
The value to subtract from iMinuend.
- piResult [out]
A pointer to the result. If the operation results in a value that overflows or underflows the capacity of the type, the function returns STATUS_INTEGER_OVERFLOW and this parameter is not valid.
This is one of a set of inline functions designed to provide arithmetic operations and perform validity checks with minimal impact on performance.
