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. FILES

devreserv(1M), attributes(5) NOTES
The commands devreserv and devfree are used to manage the availability of devices on a system. These commands do not place any con- straints 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 devreserv may concurrently use a device with a process that has reserved that device.
