fdset() -> tuple of lists with active file descriptors, readable, writeable, exceptions
Returns a tuple of three lists that can be passed to the select.select() method.
Corresponds to `curl_multi_fdset`_ in libcurl. This method extracts the
file descriptor information from a CurlMulti object. The returned lists can
be used with the ``select`` module to poll for events.
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:
apply(select.select, m.fdset() + (1,))
while 1:
ret, num_handles = m.perform()
if ret != pycurl.E_CALL_MULTI_PERFORM: break
