Subtracts one value of type USHORT from another.
NTSTATUS RtlUShortSub( _In_ USHORT usMinuend, _In_ USHORT usSubtrahend, _Out_ USHORT *pusResult );
- usMinuend [in]
The value from which usSubtrahend is subtracted.
- usSubtrahend [in]
The value to subtract from usMinuend.
- pusResult [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.
