- * int _DtGetEmbeddedClients (display, root, ppEmbeddedClients,
- * pNumEmbeddedClients)
- *
- *
- * Description:
- * -----------
- * Get the contents of the _DT_WORKSPACE_EMBEDDED_CLIENTS property
- * from a root window. This is a array of top-level windows that are
- * embedded in the front panel of the window manager. They would
- * not be picked up ordinarily by a session manager in a normal
- * search for top-level windows because they are reparented to
- * the front panel which itself is a top-level window.
- *
- *
- * Inputs:
- * ------
- * display - display
- * root - root window to get info from
- * ppEmbeddedClients - pointer to a pointer (to be returned)
- * pNumEmbeddedClients - pointer to a number (to be returned)
- *
- * Outputs:
- * -------
- * *ppEmbeddedClients - pointer to a array of window IDs (top-level
- * windows for embedded clients)
- * (NOTE: This should be freed using XFree)
- * *pNumEmbeddedClients- number of window IDs in array
- * Return - Success if property fetched ok.
- * Failure returns are from XGetWindowProperty
- *
- * Comments:
- * --------
- * Use XFree to free the returned data.
