NAME

6       curl_easy_perform - Perform a file transfer

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_perform(CURL *handle);
12

DESCRIPTION

14       This  function is called after the init and all the curl_easy_setopt(3)
15       calls are made, and will perform  the  transfer  as  described  in  the
16       options.   It  must  be  called  with  the  same handle as input as the
17       curl_easy_init call returned.
18
19       You can do any amount of calls to curl_easy_perform(3) while using  the
20       same handle. If you intend to transfer more than one file, you are even
21       encouraged to do so. libcurl will then attempt to re-use the same  con‐
22       nection for the following transfers, thus making the operations faster,
23       less CPU intense and using less network resources. Just note  that  you
24       will have to use curl_easy_setopt(3) between the invokes to set options
25       for the following curl_easy_perform.
26
27       You must never call this function simultaneously from two places  using
28       the  same  handle.  Let  the  function  return first before invoking it
29       another time. If you want parallel transfers, you must use several curl
30       handles.
31

RETURN VALUE

33       0  means  everything  was  ok,  non-zero  means  an  error  occurred as
34       <curl/curl.h>  defines.  If  the  CURLOPT_ERRORBUFFER  was   set   with
35       curl_easy_setopt  there  will  be a readable error message in the error
36       buffer when non-zero is returned.
