NOTES

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