It has a single export tag, C<:POSIX>, which will export all POSIX defined error numbers. C also makes C<%!> magic such that each element of C<%!> has a non-zero value only if C<$!> is set to that value. For example: use Errno; unless (open(FH, "/fangorn/spouse")) { if ($!{ENOENT}) { warn "Get a wife!\n"; } else { warn "This path is barred: $!"; } } If a specified constant C does not exist on the system, C<$!{EFOO}> returns C<"">. You may use C to check whether the constant is available on the system. =head1 CAVEATS Importing a particular constant may not be very portable, because the import will fail on platforms that do not have that constant. A more portable way to set C<$!> to a valid value is to use: if (exists &Errno::EFOO) { $! = &Errno::EFOO; } =head1 AUTHOR Graham Barr =head1 COPYRIGHT Copyright (c) 1997-8 Graham Barr.
