  _In_   ULONG cElems,
  _Out_  VARIANT *pvar
);

Parameters

prgn [in]

Type: const ULONGLONG*

Pointer to the source array of ULONGLONG values.

cElems [in]

Type: ULONG

The number of elements in the array pointed to by prgn.

pvar [out]

Type: VARIANT*

When this function returns, contains the initialized VARIANT structure.

Return value

Type: HRESULT

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

Remarks

Creates a VT_ARRAY | VT_UI8 variant.

Examples

The following example, to be included as part of a larger program, demonstrates how to use InitVariantFromUInt64Array.


ULONGLONG rgLongs[] = {4, 2};
VARIANT var;

HRESULT hr = InitVariantFromUInt64Array(rgLongs, ARRAYSIZE(rgLongs), &var);

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