curl_multi_init - create a multi handle
#include <curl/curl.h>
CURLM *curl_multi_init();
This function returns a pointer to a CURLM handle to be used as input to all the other multi-functions, sometimes referred to as a multi handle in some places in the documentation. This init call MUST have a corresponding call to curl_multi_cleanup(3) when the operation is complete.
/* init a multi stack */
