XkbSAScreen(3)                   XKB FUNCTIONS                  XkbSAScreen(3)



NAME
       XkbSAScreen  - Returns the screenXXX field of act converted to a signed
       int

SYNOPSIS
       int XkbSAScreen ( act )
             XkbSwitchScreenAction act;

ARGUMENTS
       - act  action from which to extract screen

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.


       c  s l l l lw(4i).  Table 1 Switch Screen Action Flags _ Flag Meaning _
       XkbSA_SwitchAbsolute     T{ 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.   T}  XkbSA_SwitchApplication  T{  If
       not set, the action should switch to another screen on the same server.
       Otherwise, it should switch to another X  server  or  application  that
       shares the same physical display.  T}

       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  character  value  for
       screen numbers in XkbSwitchScreenAction structures.

       XkbSAScreen  macro  returns  the  screenXXX field of act converted to a
       signed int.

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



NOTES
       The XkbSwitchScreen action is optional. Servers are free to ignore  the
       action  or any of its flags if they do not support the requested behav-
       ior. If the action is ignored, it behaves like  XkbSA_NoAction.  Other-
       wise, key press and key release events do not generate an event.
