ULongToIntPtr function (intsafe.h)

  • Article

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

Syntax

HRESULT ULongToIntPtr(
  [in]  ULONG   ulOperand,
  [out] INT_PTR *piResult
);

Parameters

[in] ulOperand

Type: ULONG

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.
