* descriptors to check for this. The app is recommended to pass in
* the 'easy' argument (or set it to CURL_EASY_NONE) to make libcurl
* figure out the internal structure even faster and easier. If the
* easy argument is set to something else than CURL_EASY_NONE, the
* 's' (socket) argument will be ignored by libcurl.
*
* It also informs the application about updates in the socket (file
* descriptor) status by doing none, one or multiple calls to the
* curl_socket_callback. It thus updates the status with changes
* since the previous time this function was used. If 'callback' is
* NULL, no callback will be called. A status change may also be a
* new timeout only, having the same IN/OUT status as before.
*
* If a previous wait for socket action(s) timed out, you should call
* this function with the socket argument set to
* CURL_SOCKET_TIMEOUT. If you want to force libcurl to (re-)check
* all its internal sockets, and call the callback with status for
* all sockets no matter what the previous state is, you call
* curl_multi_socket_all() instead.
*
* curl_multi_perform() is thus the equivalent of calling
* curl_multi_socket_all(handle, NULL, NULL);
*
* IMPLEMENTATION: libcurl will need an internal hash table to map
* socket numbers to internal easy handles for the cases when 'easy'
* is set to CURL_EASY_NONE.
*
* Regarding the timeout argument in the callback: it is the timeout
* (in milliseconds) for waiting on action on this socket (and the
* given time period starts when the callback is called) until you
* should call curl_multi_socket() with the timeout stuff mentioned
* above. If "actions" happens on the socket before the timeout
* happens, remember that the timout timer keeps ticking until told
* otherwise.
*
* The "what" argument has one of five values:
*
* 0 CURL_POLL_NONE (0) - register, not interested in readiness
* 1 CURL_POLL_IN - register, interested in read readiness
* 2 CURL_POLL_OUT - register, interested in write readiness
* 3 CURL_POLL_INOUT - register, interested in both
* 4 CURL_POLL_REMOVE - deregister
