Subtracts one value of type INT8 from another.
- i8Minuend [in]
The value from which i8Subtrahend is subtracted.
- i8Subtrahend [in]
The value to subtract from i8Minuend.
- pi8Result [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.
