Article
10/13/2021

Initializes a PROPVARIANT structure based on a vector of Int64 values.

Syntax

PSSTDAPI InitPropVariantFromInt64Vector(
  [in]  const LONGLONG *prgn,
  [in]  ULONG          cElems,
  [out] PROPVARIANT    *ppropvar
);

Parameters

[in] prgn

Type: const LONGLONG*

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

[in] cElems

Type: ULONG

The number of elements in the vector.

[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_I8 propvariant.

Examples

The following example, to be included as part of a larger program, demonstrates how to use InitPropVariantFromInt64Vector.

LONGLONG rgLongLongs[] = {4, 7};
PROPVARIANT propvar;

HRESULT hr = InitPropVariantFromInt64Vector(rgLongLongs, ARRAYSIZE(rgLongLongs), &propvar);

if (SUCCEEDED(hr))
{
    // propvar now is valid and has type VT_VECTOR | VT_I8.
 
    PropVariantClear(&propvar);
}
