Re: List standard Unix error codes

in reply to List standard Unix error codes

Here's a way to get the symbolic names as well:

#!/usr/bin/perl

use strict;
use warnings;

use Errno;

foreach my $err (keys (%!)) {
    $! = eval "Errno::$err";
    printf "%3d %20s %s\n", $! + 0, $err, $!
}
__END__

Note that the names are somewhat portable (it improves if you stick to the POSIX names), but the numbers and descriptions are not portable. Not even from one Unix to the other.

I only had 2 minutes to write, test and post the program, because there was a television program I wanted to see. But feel free to modify the code, and post the results. Abigail	[reply]
