|
.SH NAME
|
|
curl_easy_perform - Perform a file transfer
|
|
.SH SYNOPSIS
|
|
.B #include <curl/curl.h>
|
|
.sp
|
|
.BI "CURLcode curl_easy_perform(CURL *" handle ");"
|
|
.ad
|
|
.SH DESCRIPTION
|
|
This function is called after the init and all the \fIcurl_easy_setopt(3)\fP
|
|
calls are made, and will perform the transfer as described in the options. It
|
|
must be called with the same
|
|
.I handle
|
|
as input as the curl_easy_init call returned.
|
|
|
|
You can do any amount of calls to \fIcurl_easy_perform(3)\fP 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
|
|
\fIcurl_easy_setopt(3)\fP 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 parallel transfers, you must use several curl handles.
|
|
.SH RETURN VALUE
|
|
0 means everything was ok, non-zero means an error occurred as
|
|
.I <curl/curl.h>
|
|
defines. If the CURLOPT_ERRORBUFFER was set with
|
|
.I curl_easy_setopt
|
|
there will be a readable error message in the error buffer when non-zero is
|
|
returned.
