XkbNoteIndicatorChanges(3)		  XKB FUNCTIONS 	       XkbNoteIndicatorChanges(3)

NAME
       XkbNoteIndicatorChanges - Notes the changes in a changes structure

SYNOPSIS
       void  XkbNoteIndicatorChanges  (XkbIndicatorChangesPtr  old, XkbIndicatorNotifyEvent *new,
	      unsigned int wanted);

ARGUMENTS
       - old  XkbIndicatorChanges structure to be updated

       - new  event from which changes are to be copied

       - wanted
	      which changes are to be noted

DESCRIPTION
       Whenever an indicator changes state, the server sends  XkbIndicatorStateNotify  events  to
       all  interested	clients. Similarly, whenever an indicator's map changes, the server sends
       XkbIndicatorMapNotify events to all interested clients.

       To  receive  XkbIndicatorStateNotify   events,	use   XkbSelectEvents	with   both   the
       bits_to_change  and  values_for_bits parameters containing XkbIndicatorStateNotifyMask. To
       receive XkbIndicatorMapNotify events, use XkbSelectEvents with XkbIndicatorMapNotifyMask.

       To receive events for  only  specific  indicators,  use	XkbSelectEventDetails.	 Set  the
       event_type parameter to XkbIndicatorStateNotify or XkbIndicatorMapNotify, and set both the
       bits_to_change and values_for_bits detail parameters to a mask where  each  bit	specifies
       one  indicator,	turning  on  those bits that specify the indicators for which you want to
       receive events.

       The changed parameter is a mask that is the bitwise inclusive OR of  the  indicators  that
       have changed. If the event is of type XkbIndicatorMapNotify, changed reports the maps that
       changed. If the event is of type XkbIndicatorStateNotify, changed reports  the  indicators
       that  have changed state.  state is a mask that specifies the current state of all indica-
       tors, whether they have changed or not, for both XkbIndicatorStateNotify and IndicatorMap-
       Notify events.

       When your client application receives either a XkbIndicatorStateNotify event or XkbIndica-
       torMapNotify event, you can note the changes  in  a  changes  structure	by  calling  Xkb-
       NoteIndicatorChanges.

       The  wanted  parameter  is  the bitwise inclusive OR of XkbIndicatorMapMask and XkbIndica-
       torStateMask.  XkbNoteIndicatorChanges copies any changes reported in new and specified in
       wanted into the changes record specified by old.

STRUCTURES
       Both types of indicator events use the same structure:

       typedef struct _XkbIndicatorNotify {
	 int		type;	    /* Xkb extension base event code */
	 unsigned long	serial;     /* X server serial number for event */
	 Bool		send_event; /* True => synthetically generated */
	 Display *	display;    /* server connection where event generated */
	 Time		time;	    /* server time when event generated */
	 int		xkb_type;   /* specifies state or map notify */
	 int		device;     /* Xkb device ID, will not be XkbUseCoreKbd */
	 unsigned int	changed;    /* mask of indicators with new state or map */
	 unsigned int	state;	    /* current state of all indicators */
       } XkbIndicatorNotifyEvent;

       xkb_type  is either XkbIndicatorStateNotify or XkbIndicatorMapNotify, depending on whether
       the event is a kbIndicatorStateNotify event or kbIndicatorMapNotify event.
