Description

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

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

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:
