Could you elaborate ? > > close() can fail (generate an exception). How are you going to handle it in According to 'man 2 close', it cannot. Nearly the same is true for any resource deallocation. The only exception I can recall is wait -- but, when you don't need the exit status (and you surely don't, once you leave it to GC), you can ignore all the errors. Of course here might be a questions wish unflushed data. But still, if you don't flush the writing channel before finishing a function, you probably don't need you output to be delivered in any case. > the garbage collector?
