    dwFlags : uint, 
    ppunkAtom : Object
) : int

Parameters

dwFlags
Type: System.UInt32
[in] Selection flags. Values are taken from GetSelectedAtomFlags.

ppunkAtom
Type: System.Object%

Remarks

COM Signature

From textmgr.idl:

HRESULT IVsLayeredTextView::GetSelectedAtom(
   [in] DWORD dwFlags,
   [out] IUnknown **ppunkAtom
);

GetSelectedAtom tells a client when the selection is "at" an atomic object, "at" being defined by dwFlags. An atomic object is a special object inserted into the regular text stream, such as a hidden text banner. The returned IUnknown is a pointer to the object that corresponds to the atom; QI it for whatever custom interface might be of interest.
