NAME
       input_capabilities - query platform layer or target for input capabili-
       ties

SYNOPSIS
       captbl, ident
       input_capabilities( vid:fsrv )

DESCRIPTION
       This  function  can be used to query the	platform (default) or a	frame-
       server (providing a valid fsrv  argument) for its current set of	 input
       capabilities  in	 terms	of devices (both cases)	and data types (frame-
       server only). The returned table	is key indexed of booleans  indicating
       whether	the  type  is  supported or not. A frameserver may update this
       mask for	a segment at will. When	the mask is changed,  an  "input_mask"
       event  will  be	sent  to the frameservers assigned event handler. This
       mask will be applied to samples provided	through	target_input . For the
       platform, the set may also change when devices are added	and removed in
       response	to a device appearing and removing. The	set of provided	or ac-
       cepted devices may be zero, one or many of  the	following:  "keyboard,
       "mouse",	 "game", "touch", "position", "orientation", "eyetracker". The
       set of accepted datatypes may be	zero, one or many  of  the  following:
       "analog", "digital", "translated", "touch", "eyes".

EXAMPLE
       function	input_capabilities0()
	     for k,v in	pairs(input_capabilities()) do
		   print(k, v);
	     end
       end
