Operating Systems HP-UX How to Lock In HP-UX Post 302078988 by jim mcnamara on Thursday 6th of July 2006 06:55:38 AM

When you drive a car and come to a traffic light - and the light is green - you go thru the intersection. If the light is red, you stop. The traffic light works because everyone agrees to stop on red, well most of the time.

A system without mandatory locking works just like the traffic light. Every program accessing the file has to agree to check the lock and abide by it.

A not-very-good option:
1. mv the file to a directory you own while your program accesses it.
2. mv the file back to where it belongs when you are done.

What problem are you trying to solve?

This manual page was edited by Michael Weller <eowmob@exp-math.uni-essen.de>. The exact source of the referenced function as well as of the original documentation is unknown. It is very likely that both are at least to some extent are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>. Occasionally this might be wrong.
