Syntax
NTSTATUS RtlIntSub(
[in] INT iMinuend,
[in] INT iSubtrahend,
INT *piResult
);
Parameters
[in] iMinuend
The value from which iSubtrahend is subtracted.
[in] iSubtrahend
The value to subtract from iMinuend.
piResult
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:
- RtlInt32Sub
- RtlLong32Sub
