curl_easy_perform(3)                           libcurl Manual                           curl_easy_perform(3)

       curl_easy_perform - Perform a file transfer

       #include <curl/curl.h>

       CURLcode curl_easy_perform(CURL *handle);

       This  function is called after the init and all the curl_easy_setopt(3) calls are made, and will per-form perform
       form the transfer as described in the options.  It must be called with the same handle  as  input  as
       the curl_easy_init call returned.

       You  can do any amount of calls to curl_easy_perform(3) while using the same handle. If you intend to
       transfer more than one file, you are even encouraged to do so. libcurl will then  attempt  to  re-use
       the  same connection for the following transfers, thus making the operations faster, less CPU intense
       and using less network resources. Just note that you will have to use curl_easy_setopt(3) between the
       invokes to set options for the following curl_easy_perform.

       You must never call this function simultaneously from two places using the same handle. Let the func-tion function
       tion return first before invoking it another time. If you want parallel transfers, you must use  sev-eral several
       eral curl handles.

       0  means  everything  was  ok, non-zero means an error occurred as <curl/curl.h> defines. If the CUR-LOPT_ERRORBUFFER CURLOPT_ERRORBUFFER
       LOPT_ERRORBUFFER was set with curl_easy_setopt there will be a readable error message  in  the  error
       buffer when non-zero is returned.
