RtlInt8Sub function (ntintsafe.h)
Subtracts one value of type INT8 from another.
Syntax
NTSTATUS RtlInt8Sub(
[in] INT8 i8Minuend,
[in] INT8 i8Subtrahend,
[out] INT8 *pi8Result
);
Parameters
[in] i8Minuend
The value from which i8Subtrahend is subtracted.
[in] i8Subtrahend
The value to subtract from i8Minuend.
[out] pi8Result
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.
