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
  modifiers 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:
