ULongPtrToIntPtr function

-description

Converts a value of type ULONG_PTR to a value of type INT_PTR.

-parameters

-param ulOperand [in]

Type: ULONG_PTR

The value to be converted.

-param piResult [out]

Type: INT_PTR*

A pointer to the converted value. In the case where the conversion causes a truncation of the original value, the function returns INTSAFE_E_ARITHMETIC_OVERFLOW and this parameter is not valid.

-returns

Type: HRESULT

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

-remarks

This is one of a set of inline functions designed to provide type conversions and perform validity checks with minimal impact on performance.
