<H2>DESCRIPTION</H2><PRE>
|
|
This function is called after the init and all the
|
|
curl_easy_setopt() calls are made, and will perform the
|
|
transfer as described in the options. It must be called
|
|
with the same <I>handle</I> as input as the curl_easy_init call
|
|
returned.
|
|
|
|
libcurl version 7.7 or later (for older versions see
|
|
below): You can do any amount of calls to curl_easy_per-
|
|
form() 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 connec-
|
|
tion for the following transfers, thus making the opera-
|
|
tions faster, less CPU intense and using less network
|
|
resources. Just note that you will have to use
|
|
<I>curl</I><B>_</B><I>easy</I><B>_</B><I>setopt</I> 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 function return
|
|
first before invoking it another time. If you want paral-
|
|
lel transfers, you must use several curl handles.
|
|
|
|
Before libcurl version 7.7: You are only allowed to call
|
|
this function once using the same handle. If you want to
|
|
do repeated calls, you must call curl_easy_cleanup and
|
|
curl_easy_init again first.

<H2>RETURN VALUE</H2><PRE>
|
|
0 means everything was ok, non-zero means an error
|
|
occurred as <I><curl/curl.h></I> defines. If the CURLOPT_ERROR-
|
|
BUFFER was set with <I>curl</I><B>_</B><I>easy</I><B>_</B><I>setopt</I> there will be a read-
|
|
able error message in the error buffer when non-zero is
|
|
returned.
