Subtracts one value of type PTRDIFF_T from another.
The value from which Subtrahend is subtracted.
The value to subtract from Minuend.
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.
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.
This is one of a set of inline functions designed to provide arithmetic operations and perform validity checks with minimal impact on performance.
