Hi TJ, strangely, there isn't, but instead a return code of -1 means poll() throwing an error – namely "Interrupted system call" (errno=4).
*poll*() returns the number of descriptors that are ready for I/O, or -1 if an error occurred. If the time limit expires, *poll*() returns 0. If *poll*() returns with an error, including one due to an interrupted call, the fds array will be unmodified. (http://www.daemon-systems.org/man/poll.2.html) Seemingly, this has something to do with a property of session->socket_fd Thanks for your interest, Nick 2012/4/26 TJ Saunders <t...@castaglia.org> > > > With your method, the error message is 'Resource temporarily unavailable' > > (!) > > > > Digging deeper, I found two remarkable things: > > > > 1) session->api_timeout == 0 > > ... might be due to the interface (no session->api_timeout set??), but > this > > doesn't seem to lead to program interruption. > > > > 2) in session.c::_libssh2_wait_socket(), line 632 – HAVE_POLL holds... > > > > rc = poll(sockets, 1, has_timeout?ms_to_next: -1); > > > > returns -1, which directly leads to LIBSSH2_ERROR_TIMEOUT. > > > > Any idea?? > > From that "Main: TIMEOUT" message you reported, it sounds like your > application (which is using libssh2) has some sort of overall > timeout/timer set.
