Unlike the C interface which deals with # milliseconds as integers, the python interface uses seconds as floats for the # timeout. Therefore we need to use the Python float (C double) value that # gives 0x7FFFFFFF if multiplied by 1000.0 and cast into an integer. # # This calculation should be precise enough to get a value of 0x7FFFFFFF on the # C side. If not, it will still amount to a very long time (not quite 25 days) # which should be enough for all intents and purposes. method_call_no_timeout = 0x7FFFFFFF / 1000.0
