LOCK(2) System Calls Manual 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 considered a permanent
part of the system.
