trapping an error is easy: 
eval {
  # your code to be trapped
  # ... or die "error message 123"
}
if ($@) {
  # do your error checking, such as $@=~/error message 123/
}

As was announced perl6 will change "eval{BLOCK}" to "try{BLOCK}" when it is used for trapping an error, to be more consistent.

It is interesting though to have a possibility to check whether writting is currently performing.

I think it is somewhere in IO::* modules (may be in IO::Handle), but unfortunately can not help with this right now.

Have a nice day,
