ULongPtrToSSIZET function

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

Syntax

HRESULT ULongPtrToSSIZET(
  _In_  ULONG_PTR ulOperand,
  _Out_ SSIZE_T   *pcbResult
);

Parameters

  • ulOperand [in]
    Type: ULONG_PTR

    The value to be converted.

  • pcbResult [out]
    Type: SSIZE_T*

    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.
