LOCK(2) (local) LOCK(2)
NAME
lock - lock a process in primary memory
SYNOPSIS
lock(flag)
DESCRIPTION
If the flag argument is non-zero, the process executing this
call will not be swapped except if it is required to grow.
If the argument is zero, the process is unlocked. This call
may only be executed by the super-user.
BUGS
Locked processes interfere with the compaction of primary
memory and can cause deadlock. This system call is not con-
sidered a permanent part of the system.
