InitPropVariantFromFileTimeVector function (propvarutil.h)

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

Syntax

PSSTDAPI InitPropVariantFromFileTimeVector(
  [in, optional] const FILETIME *prgft,
  [in]           ULONG          cElems,
  [out]          PROPVARIANT    *ppropvar
);

Parameters

[in, optional] prgft

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.

[in] cElems

Type: ULONG

The number of vector elements.

[out] ppropvar

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);
}
