NAME
       CURLMOPT_TIMERDATA - custom pointer to pass to timer callback

SYNOPSIS
       #include <curl/curl.h>

       CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_TIMERDATA, void *pointer);

DESCRIPTION
       A  data  pointer  to  pass  to  the  timer  callback set with the CURL-
       MOPT_TIMERFUNCTION(3) option.

       This pointer will not be touched by libcurl but will only be passed  in
       to the timer callbacks's userp argument.

DEFAULT
       NULL

PROTOCOLS
       All

EXAMPLE
       static gboolean timeout_cb(gpointer user_data)
       {
         int running;
         if(user_data) {
           g_free(user_data);
           curl_multi_setopt(curl_handle, CURLMOPT_TIMERDATA, NULL);
         }
         curl_multi_socket_action(multi, CURL_SOCKET_TIMEOUT, 0, &running);
         return G_SOURCE_REMOVE;
       }

       static int timerfunc(CURLM *multi, long timeout_ms, void *userp)
       {
         guint *id = userp;

         if(id)
           g_source_remove(*id);

         /* -1 means we should just delete our timer. */
         if(timeout_ms == -1) {
           g_free(id);
           id = NULL;
         }
         else {
           if(!id)
             id = g_new(guint, 1);
           *id = g_timeout_add(timeout_ms, timeout_cb, id);
         }
         curl_multi_setopt(multi, CURLMOPT_TIMERDATA, id);
         return 0;
       }

       curl_multi_setopt(multi, CURLMOPT_TIMERFUNCTION, timerfunc);

AVAILABILITY
       Added in 7.16.0

RETURN VALUE
       Returns  CURLM_OK  if the option is supported, and CURLM_UNKNOWN_OPTION
       if not.
