231=head1 NAME
232
233Errno - System errno constants
234
235=head1 SYNOPSIS
236
237 use Errno qw(EINTR EIO :POSIX);
238
239=head1 DESCRIPTION
240
241C<Errno> defines and conditionally exports all the error constants
242defined in your system C<errno.h> include file. It has a single export
243tag, C<:POSIX>, which will export all POSIX defined error numbers.
244
245C<Errno> also makes C<%!> magic such that each element of C<%!> has a
246non-zero value only if C<$!> is set to that value. For example:
247
248 use Errno;
249
250 unless (open(FH, "/fangorn/spouse")) {
251 if ($!{ENOENT}) {
252 warn "Get a wife!\n";
253 } else {
254 warn "This path is barred: $!";
255 }
256 }
257
258If a specified constant C<EFOO> does not exist on the system, C<$!{EFOO}>
259returns C<"">. You may use C<exists $!{EFOO}> to check whether the
260constant is available on the system.
261
262=head1 CAVEATS
263
264Importing a particular constant may not be very portable, because the
265import will fail on platforms that do not have that constant. A more
266portable way to set C<$!> to a valid value is to use:
267
268 if (exists &Errno::EFOO) {
269 $! = &Errno::EFOO;
270 }
