name : multi_select.rst select([timeout]) -> number of ready file descriptors or -1 on timeout Returns result from doing a select() on the curl multi file descriptor with the given timeout. This is a convenience function which simplifies the combined use of ``fdset()`` and the ``select`` module. Example usage:: import pycurl c = pycurl.Curl() c.setopt(pycurl.URL, "https://curl.haxx.se") m = pycurl.CurlMulti() m.add_handle(c) while 1: ret, num_handles = m.perform() if ret != pycurl.E_CALL_MULTI_PERFORM: break while num_handles: ret = m.select(1.0) if ret == -1: continue while 1: ret, num_handles = m.perform() if ret != pycurl.E_CALL_MULTI_PERFORM: break
