InitPropVariantFromFileTimeVector function

Initializes a PROPVARIANT structure from a specified vector of FILETIME values.

Syntax

HRESULT InitPropVariantFromFileTimeVector(
  _In_opt_ const FILETIME    *prgft,
  _In_           ULONG       cElems,
  _Out_          PROPVARIANT *ppropvar
);

Parameters

prgft [in, optional]

Type: const FILETIME*

Pointer to the date and time as a FILETIME vector. If this value is NULL, the elements pointed to by the cafiletime.pElems structure member is initialized with (FILETIME)0.

cElems [in]

Type: ULONG

The number of vector elements.

ppropvar [out]

Type: PROPVARIANT*

When this function returns, contains the initialized PROPVARIANT structure.

Return value

Type: HRESULT

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

Remarks

Creates a VT_VECTOR | VT_FILETIME propvariant.

Examples

The following example, to be included as part of a larger program, demonstrates how to use InitPropVariantFromFileTimeVector.

// FILETIME rgFileTime[];
// Assume variable rgFileTime is initialized and valid.
PROPVARIANT propvar;

HRESULT hr = InitPropVariantFromFileTimeVector(rgFileTime, ARRAYSIZE(rgFileTime), &propvar);

if (SUCCEEDED(hr))
{
    // propvar now is valid and has type VT_VECTOR | VT_FILETIME.
 
    PropVariantClear(&propvar);
}
