=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: $!";
|
|
}
|
|
}
