$EXTENDED_OS_ERROR
$^E
More specific information about the last system error than that provided by
$!, if available. (If not, it's just $! again, except under
OS/2.) At the moment, this differs from $! under only
VMS and
OS/2, where it provides the
VMS status value from the last system error, and
OS/2 error code of the last call to
OS/2
API which was not directed via
CRT. The caveats mentioned in the description of
$! apply here, too. (Mnemonic: Extra error explanation.)
Note that under
OS/2 $! and $^E do not track each other, so if an OS/2-specific call is performed, you may
need to check both.
