InitVariantFromUInt32Array function (propvarutil.h)

Initializes a VARIANT structure with an array of unsigned 32-bit integer values.

Syntax

PSSTDAPI InitVariantFromUInt32Array(
  [in]  const ULONG *prgn,
  [in]  ULONG       cElems,
  [out] VARIANT     *pvar
);

Parameters

[in] prgn

Type: const ULONG*

Pointer to the source array of ULONG values.

[in] cElems

Type: ULONG

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

[out] pvar

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_UI4 variant.

Examples

The following example, to be included as part of a larger program, demonstrates how to use InitVariantFromUInt32Array.

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

HRESULT hr = InitVariantFromUInt32Array(rgLongs, ARRAYSIZE(rgLongs), &var);

if (SUCCEEDED(hr))                            
{
    // var now is valid and has type VT_ARRAY | VT_UI4.
    VariantClear(&propvar);
}
