RtlUIntPtrSub function (ntintsafe.h)
Subtracts one value of type UINT_PTR from another.
Syntax
NTSTATUS RtlUIntPtrSub(
[in] UINT_PTR uMinuend,
[in] UINT_PTR uSubtrahend,
[out] UINT_PTR *puResult
);
Parameters
[in] uMinuend
The value from which uSubtrahend is subtracted.
[in] uSubtrahend
The value to subtract from uMinuend.
[out] puResult
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.
Return value
Returns STATUS_SUCCESS if the operation is successful.
See the implementation of this helper function in ntintsafe.h
in the WDK for possible error return values.
Remarks
This is one of a set of inline functions designed to provide arithmetic operations and perform validity checks with minimal impact on performance.
This function uses the following alternate name:
- RtlUIntPtrSub
- RtlULongPtrSub
- RtlDWordPtrSub
- RtlSIZETSub
- RtlDWordLongSub
- RtlULong64Sub
- RtlDWord64Sub
- RtlUInt64Sub
