Re: Detecting the close() of named pipes

Have you tried the -e file test?

Example:

open(my $z, '| more'); # stupid call, just an example!
print ("Exists: ", -e $z, "\n");
close($z);
print ("\nExists: ", -e $z, "\n");

Should return:

Exists: 1
Exists:

When I close() the named pipe, it seems to leave the files there though... they still Exist. I'm using POSIX:mknod to make it.	[reply]

If you don't remove them, there they are. As usual ;-) Named pipes are files, you have to do the cleanup yourself, as opposed to anonymous pipes. The latter are reaped by the OS. See pipe for those. --shmem _($_=" "x(1<<5)."?\n".q·/)Oo.
