XkbLockModifiers(3)              XKB FUNCTIONS             XkbLockModifiers(3)



NAME
       XkbLockModifiers  -   Locks  and unlocks any of the eight real keyboard
       modifiers

SYNOPSIS
       Bool XkbLockModifiers ( display, device_spec, affect, values )
             Display *display;
             unsigned int device_spec;
             unsigned int affect;
             unsigned int values;

ARGUMENTS
       display
              connection to the X server

       device_spec
              device ID, or XkbUseCoreKbd

       affect mask of real modifiers whose lock state is to change

       values 1 => lock, 0 => unlock; only for modifiers selected by affect

DESCRIPTION
       XkbLockModifiers sends a request to the server to lock the  real  modi-
       fiers  selected  by both affect and values and to unlock the real modi-
       fiers selected by affect, but not selected by values.  XkbLockModifiers
       does  not  wait  for  a  reply  from the server. It returns True if the
       request was sent, and False otherwise.

       The functions in this section that change the use of  modifiers  use  a
       mask in the parameter affect. It is a bitwise inclusive OR of the legal
       modifier masks:

RETURN VALUES
       True           The  XkbLockModifiers function returns True if a request
                      is sent  to  the  server  to  lock  the  real  modifiers
                      selected  by  both  affect  and values and to unlock the
                      real modifiers selected by affect, but not  selected  by
                      values.

                      request was not sent.
