NAME

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

SYNOPSIS

       Bool XkbLockModifiers (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 modifiers selected by both affect and values and to unlock the real modi-

       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:
