UIntPtrSub function (intsafe.h)
Subtracts one value of type UINT_PTR from another.
Syntax
HRESULT UIntPtrSub(
[in] UINT_PTR uMinuend,
[in] UINT_PTR uSubtrahend,
[out] UINT_PTR *puResult
);
Parameters
[in] uMinuend
Type: UINT_PTR
The value from which uSubtrahend is subtracted.
[in] uSubtrahend
Type: UINT_PTR
The value to subtract from uMinuend.
[out] puResult
Type: UINT_PTR*
A pointer to the result. If the operation results in a value that overflows or underflows the capacity of the type, the function returns INTSAFE_E_ARITHMETIC_OVERFLOW and this parameter is not valid.
