create_connection() is documented as a coroutine. That means you
should be able to catch the error inside another coroutine using a
try/except:
@async.coroutine
def start_it(...):
try:
yield from asyncio.create_connection(...)
except OSError:
<handle error>
You can also convert it to a Future using asyncio.async() and add a
done-callback to check for and handle errors:
def error_handler(f):
try:
f.result()
except OSError:
<handle error>
f = asyncio.async(asyncio.create_connection(...))
f.add_done_callback(error_handler)
Good luck!
