InitPropVariantFromUInt16Vector function (propvarutil.h)

Initializes a PROPVARIANT structure based on a vector of 16-bit unsigned integer values.

Syntax

PSSTDAPI InitPropVariantFromUInt16Vector(
  [in]  const USHORT *prgn,
  [in]  ULONG        cElems,
  [out] PROPVARIANT  *ppropvar
);

Parameters

[in] prgn

Type: const USHORT*

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

[in] cElems

Type: ULONG

Number of elements in the vector pointed to by prgn.

[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_UI2 propvariant.

Examples

The following example, to be included as part of a larger program, demonstrates how to use InitPropVariantFromUInt16Vector.

USHORT rgShorts[] = {4, 7};
PROPVARIANT propvar;

HRESULT hr = InitPropVariantFromUInt16Vector(rgShorts, ARRAYSIZE(rgShorts), &propvar);

if (SUCCEEDED(hr))
{
    // propvar now is valid and has type VT_VECTOR | VT_UI2.
     PropVariantClear(&propvar);
}
