This init call MUST have a corresponding call to curl_multi_cleanup(3) when the operation is complete. # EXAMPLE ~~~c int main(void) { /* init a multi stack */ CURLM *multi = curl_multi_init(); CURL *curl = curl_easy_init(); CURL *curl2 = curl_easy_init(); /* add individual transfers */ curl_multi_add_handle(multi, curl); curl_multi_add_handle(multi, curl2); } ~~~ # RETURN VALUE If this function returns NULL, something went wrong and you cannot use the other curl functions.
