InitPropVariantFromUInt64Vector function

Initializes a PROPVARIANT structure based on a vector of 64-bit unsigned integers.

Syntax


HRESULT InitPropVariantFromUInt64Vector(
  _In_   const ULONGLONG *prgn,
  _In_   ULONG cElems,
  _Out_  PROPVARIANT *ppropvar
);

Parameters

prgn [in]

Type: const ULONGLONG*

Pointer to a source vector of ULONGLONG values. If this parameter is NULL, the PROPVARIANT is initialized with zeros.

cElems [in]

Type: ULONG

Number of elements in the vector pointed to by prgn.

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_UI8 propvariant.

Examples

The following example, to be included as part of a larger program, demonstrates how to use InitPropVariantFromUInt64Vector.


ULONGLONG rgLongs[] = {4, 7};
PROPVARIANT propvar;

HRESULT hr = InitPropVariantFromUInt32Vector(rgLongs, ARRAYSIZE(rgLongs), &propvar);

if (SUCCEEDED(hr))
{
    // propvar now is valid and has type VT_VECTOR | VT_UI8.
    PropVariantClear(&propvar);
}
