- Errno defines and conditionally exports all the error
- constants defined in your system errno.h include file. It
- has a single export tag, :POSIX, which will export all POSIX
- defined error numbers.
-
- Errno also makes %! magic such that each element of %! has a
- non-zero value only if $! is set to that value, eg
-
- use Errno;
-
- unless (open(FH, "/fangorn/spouse")) {
- if ($!{ENOENT}) {
- warn "Get a wife!\n";
- } else {
- warn "This path is barred: $!";
- }
- }
