Subtracts one value of type LONG from another.
Syntax
NTSTATUS RtlLongSub(
[in] LONG lMinuend,
[in] LONG lSubtrahend,
[out] LONG *plResult
);
Parameters
[in] lMinuend
The value from which lSubtrahend is subtracted.
[in] lSubtrahend
The value to subtract from lMinuend.
[out] plResult
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.
