Detailed Description

This file implements a mapping from remote XInput event types to Xdmx XInput event types.

The exglobals.h file defines global server-side variables with names Device* to be integers that hold the value of the type of the server-side XInput extension event.

The client-side X11/extensions/XInput.h file defines macros with THE EXACT SAME Device* names!

Using those macros to extract remote server event type values from the (opaque) XDevice structure is appropriate, but makes a direct mapping to the Device* integers impossible. So we use the normalized XI_Device* names for these routines.

void dmxMapClear

DMXLocalInputInfoPtr

dmxLocal

)

Remove all mappings there were inserted with dmxMapInsert.

void dmxMapInsert	(	DMXLocalInputInfoPtr	dmxLocal,
		int	remoteEvent,
		int	serverEvent
	)

Create a mapping from remoteEvent to serverEvent. The remoteEvent is the type returned from the remote server. The serverEvent is from the XI_* list of events in include/extensions/XIproto.h.

int dmxMapLookup	(	DMXLocalInputInfoPtr	dmxLocal,
		int	remoteEvent
	)

Lookup a mapping for remoteEvent. The remoteEvent is the type returned from the remote server. The return value is that which was passed into dmxMapInsert (i.e., a value from the XI_* list in include/extensions/XIproto.h). If a mapping is not available, -1 is returned.
