UIntPtrSub function

Subtracts one value of type UINT_PTR from another.

Syntax

C++
Copy 

HRESULT UIntPtrSub(
  _In_  UINT_PTR uMinuend,
  _In_  UINT_PTR uSubtrahend,
  _Out_ UINT_PTR *puResult
);

The value to subtract from uMinuend.

puResult [out]

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.

Return value
