curl_multi_init (3)

#include <curl/curl.h>

CURLM *curl_multi_init( );

This function returns 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.

If this function returns NULL, something went wrong and you cannot use the other curl functions.
