NAME
       plm - pseudo lock manager device interface

DESCRIPTION
       This character special device provides a communications path between
       the operating system kernel and the lockd(1M) network daemon.  The
       special file /dev/plm is open-ed(2) by lockd(1M), and serves as a
       point for passing record lock requests and replies out of and into
       the operating system kernel.  Lockd(1M) is the only program that
       should ever access plm.  In order for remote record locking services
       to be provided, the pseudo device driver entry plm() must be listed
       in the system(4) file before configuring the system.

FILES
       /dev/plm       Special file for remote record locking service.

SEE ALSO
       config(1M), lockd(1M), open(2), system(4).
