Operating Systems HP-UX How to Lock In HP-UX Post 302079174 by Perderabo on Friday 7th of July 2006 08:49:27 AM

I put a lengthy sleep in my code so the lock stayed around for a while. While a manditory lock is in effect no process can write to the file. So when I tried a simple cp to the file I got:
$ cp datafile2 datafile
cp: cannot create datafile: Resource temporarily unavailable

But I did that quickly, while the locking process was still asleep.
