|
|
* 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.
