=head1 NAME

Errno - System errno constants

=head1 SYNOPSIS

    use Errno qw(EINTR EIO :POSIX);

=head1 DESCRIPTION

C<Errno> defines and conditionally exports all the error constants
defined in your system C<errno.h> include file. It has a single export
tag, C<:POSIX>, which will export all POSIX defined error numbers.

C<Errno> also makes C<%!> magic such that each element of C<%!> has a non-zero
value only if C<$!> is set to that value, eg

    use Errno;

    unless (open(FH, "/fangorn/spouse")) {
        if ($!{ENOENT}) {
            warn "Get a wife!\n";
        } else {
            warn "This path is barred: $!";
        }
    }
