DESCRIPTION

14       The  function comedi_lock() reserves a subdevice for use by the current
15       process.  While the lock is held, no other process is allowed to  read,
16       write,  or  configure that subdevice, although other processes can read
17       information  about  the  subdevice.   The   lock   is   released   when
18       comedi_unlock() is called, or the device is closed.
