ULongPtrToIntPtr function (intsafe.h)

  • Article

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

Syntax

HRESULT ULongPtrToIntPtr(
  [in]  ULONG_PTR ulOperand,
  [out] INT_PTR   *piResult
);

Parameters

[in] ulOperand

Type: ULONG_PTR

The value to be converted.

[out] piResult

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.

Return value

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.
