From doc/nn_survey.txt [0]: > When the survey deadline expires, receive will return ETIMEDOUT error. But it seems to me the error is actually EFSM in this case, as it is e.g. checked for in tests/survey.c [1]. Is the documentation wrong here? With nn_survey, when is the error EFSM and when is it ETIMEDOUT (if at all)? Please clarify. Thanks, Daniel [0] https://github.com/nanomsg/nanomsg/blob/6a333ae616c9dd1893c2a47e2b5a8b52b433fa77/doc/nn_survey.txt#L23-L27 [1] https://github.com/nanomsg/nanomsg/blob/6a333ae616c9dd1893c2a47e2b5a8b52b433fa77/tests/survey.c#L71
