    Type: System.UInt32
    [in] Flags specifying how the word extent is determined. For a list of dwFlags values, see WORDEXTFLAGS.

Remarks

COM Signature

From textmgr.idl:

HRESULT IVsTextView::GetWordExtent(
   [in] long iLine,
   [in] CharIndex iCol,
   [in] DWORD dwFlags,
   [out] TextSpan *pSpan
);

The word extent is wherever the editor determines the word boundary to be. For example, if you place your cursor in within a word and then double-click, the core text editor assumes that the word extent is that entire word.
