* USAGE:
* wineclipsrv [selection_mask] [debugClass_mask] [clearAllSelections]
*
* The optional selection-mask argument is a bit mask of the selection
* types to be acquired. Currently two selections are supported:
* 1. PRIMARY (mask value 1)
* 2. CLIPBOARD (mask value 2).
*
* debugClass_mask is a bit mask of all debugging classes for which messages
* are to be output. The standard Wine debug class set FIXME(1), ERR(2),
* WARN(4) and TRACE(8) are supported.
*
* If clearAllSelections == 1 *all* selections are lost whenever a SelectionClear
* event is received.
*
* If no arguments are supplied the server aquires all selections. (mask value 3)
* and defaults to output of only FIXME(1) and ERR(2) messages. The default for
* clearAllSelections is 0.
*
* NOTES: * NOTES:
* This file contains the implementation for the Clipboard server *
* The Wine Clipboard Server is a standalone XLib application whose
* purpose is to manage the X selection when Wine exits.
* The server itself is started automatically with the appropriate
* selection masks, whenever Wine exits after acquiring the PRIMARY and/or
* CLIPBOARD selection. (See X11DRV_CLIPBOARD_ResetOwner)
* When the server starts, it first proceeds to capture the selection data from
* Wine and then takes over the selection ownership. It does this by querying
* the current selection owner(of the specified selections) for the TARGETS
* selection target. It then proceeds to cache all the formats exposed by
* TARGETS. If the selection does not support the TARGETS target, or if no
* target formats are exposed, the server simply exits.
* Once the cache has been filled, the server then actually acquires ownership
* of the respective selection and begins fielding selection requests.
* Selection requests are serviced from the cache. If a selection is lost the
* server flushes its internal cache, destroying all data previously saved.
* Once ALL selections have been lost the server terminates.
* *
