PtrdiffTToSIZET function

Converts a value of type ptrdiff_t to a value of type SIZE_T.

Syntax

c++

HRESULT PtrdiffTToSIZET(
  _In_  ptrdiff_t cbOperand,
  _Out_ SIZE_T    *pcbResult
);

Parameters

• cbOperand [in]
  Type: ptrdiff_t

  The value to be converted.

• pcbResult [out]
  Type: SIZE_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.
