curl_easy_perform(3)            libcurl Manual            curl_easy_perform(3)



NAME
       curl_easy_perform - perform a blocking file transfer

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_perform(CURL *easy_handle);

DESCRIPTION
       Invoke    this   function   after   curl_easy_init(3)   and   all   the
       curl_easy_setopt(3) calls are made, and it  performs  the  transfer  as
       described  in  the options. It must be called with the same easy_handle
       as input as the curl_easy_init(3) call returned.

       curl_easy_perform(3) performs the entire request in a  blocking  manner
       and  returns when done, or earlier if it fails. For non-blocking behav‐
       ior, see curl_multi_perform(3).

       You can do any amount of calls to curl_easy_perform(3) while using  the
       same easy_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 easy_handle. Let the function return first before invoking it
       another time. If you want parallel transfers, you must use several curl
       easy_handles.

       A  network transfer moves data to a peer or from a peer. An application
       tells libcurl how to receive data  by  setting  the  CURLOPT_WRITEFUNC‐
       TION(3)  and CURLOPT_WRITEDATA(3) options. To tell libcurl what data to
       send, there are a few more alternatives but two common  ones  are  CUR‐
       LOPT_READFUNCTION(3) and CURLOPT_POSTFIELDS(3).

       While  the easy_handle is added to a multi handle, it cannot be used by
       curl_easy_perform(3).

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         CURLcode res;
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
         res = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

AVAILABILITY
       Always

RETURN VALUE
       CURLE_OK (0) means everything was OK, non-zero means an error  occurred
       as <curl/curl.h> defines - see libcurl-errors(3). If the CURLOPT_ERROR‐
       BUFFER(3) was set with curl_easy_setopt(3) there  will  be  a  readable
       error message in the error buffer when non-zero is returned.
