);

Parameters

Examples

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


// void *pv;
// UINT cb;
// Assume variable pv and cb are initialized and valid. pv points to a buffer  
// and cb contains the size of the buffer in bytes.
PROPVARIANT propvar;

HRESULT hr = InitPropVariantFromBuffer(pv, cb, &propvar);

if (SUCCEEDED(hr))
{
    // propvar now is valid and has type VT_VECTOR | VT_UI1.
 
    PropVariantClear(&propvar);
}
