XkbSASetScreen(3)			  XKB FUNCTIONS 			XkbSASetScreen(3)

NAME
       XkbSASetScreen - Sets the screenXXX field of act from s

SYNOPSIS
       void XkbSASetScreen (XkbSwitchScreenAction act, int s);

ARGUMENTS
       - act  action in which to set screenXXX

       - s    value to set in screenXXX

DESCRIPTION
       Actions associated with the XkbSwitchScreen action structure change the active screen on a
       multiscreen display.

       The type field of the XkbSwitchScreenAction structure should always be XkbSA_SwitchScreen.

       The flags field is composed of the bitwise inclusive OR of the masks shown in Table 1.

		       Table 1 Switch Screen Action Flags
       -------------------------------------------------------------------
       Flag			 Meaning
       -------------------------------------------------------------------
       XkbSA_SwitchAbsolute	 If set, the screenXXX	field  represents
				 the  index of the new screen. Otherwise,
				 it represents an offset from the current
				 screen to the new screen.
       XkbSA_SwitchApplication	 If  not set, the action should switch to
				 another screen on the same server.  Oth-
				 erwise,  it  should  switch to another X
				 server or application	that  shares  the
				 same physical display.

       The  screenXXX  field  is  a signed character value that represents either the relative or
       absolute screen index, depending on the state of the XkbSA_SwitchAbsolute bit in the flags
       field. Xkb provides the following macros to convert between the integer and signed charac-
       ter value for screen numbers in XkbSwitchScreenAction structures.

STRUCTURES
	   typedef struct _XkbSwitchScreenAction {
	       unsigned char	type;	     /* XkbSA_SwitchScreen */
	       unsigned char	flags;	     /* controls screen switching */
	       char		screenXXX;   /* screen number or delta */
	   } XkbSwitchScreenAction;

NOTES
       This action is optional. Servers are free to ignore the action or any of its flags if they
       do  not	support  the  requested  behavior.  If	the  action  is  ignored, it behaves like
       XkbSA_NoAction. Otherwise, key press and key release events do not generate an event.
