Hi,
I need to modify some code that check for the existance of a lockfile:
unless (&shlock("$somedir/.cache.LOCK")) {
print "$main'program_name: cache already running\n" if $verbose;
exit;
}
I don't want to "exit" if I find the lock there. What I need to do is
back off for a short period of time (a few seconds?) then try again, until
the lockfile is gone.
I'm not sure what might be the best way to approach this. I'm not comfy
with an indefinite loop, where if there is some problem removing the lockfile,
my program would wait forever. I'd rather try for a few minutes, then exit
with some error.
Any pearls of wisdom out there? I could use a boost...
Thanks,
deb
