Can someone throw more light on what’s

Errno::EBADF in the code -  
begin

# Read stuff etc.

rescue Errno::EBADF

# Whatever

end

Thanks.

Those come from `errno''. See the errno(3) manpage. And, from that man:`EBADF Bad file descriptor (POSIX.1)’’

However, I have no idea what would cause it. Possibly closing a FD  
and then trying to use it later (think C/low-level) but, I’m note  
sure.
