NAME
       devfree - release devices from exclusive use

SYNOPSIS
       devfree key [device]...

DESCRIPTION
       devfree releases devices from exclusive use. Exclusive use is requested
       with the command devreserv.

       When  devfree is invoked with only the key argument,  it	 releases  all
       devices that have been reserved for that	 key. When called with key and
       device arguments,  devfree releases  the specified  devices  that  have
       been reserved with that	key.

OPERANDS
       The following operands are supported:

       device
		 Defines  device that this command will release from exclusive
		 use. device can be the pathname of the device or  the	device
		 alias.

       key
		 Designates the unique key on which the device was reserved.

EXIT STATUS
       The following exit values are returned:

       0
	    Successful completion.

       1
	    Command  syntax  was  incorrect, an invalid option was used, or an
	    internal error occurred.

       2
	    Device table or device reservation table could not be  opened  for
	    reading.

       3
	    Reservation	 release could not be completely fulfilled because one
	    or more of the devices was not reserved or was not reserved on the
	    specified key.

NOTES
       The  commands devreserv and devfree are used to manage the availability
       of devices on a system. These commands do not place any constraints  on
       the  access to the device. They serve only as a centralized bookkeeping
       point for those who wish to use them. Processes that do not use	devre‐
       serv  may  concurrently	use  a device with a process that has reserved
       that device.
