.SH NAME
|
|
curl_easy_perform - Perform a file transfer
|
|
.SH SYNOPSIS
|
|
.B #include <curl/curl.h>
|
|
.sp
|
|
.BI "CURLcode curl_easy_perform(CURL *" easy_handle ");"
|
|
.ad
|
|
.SH DESCRIPTION
|
|
Invoke this function after \fIcurl_easy_init(3)\fP 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 \fBeasy_handle\fP as
|
|
input as the \fIcurl_easy_init(3)\fP call returned.
|
|
|
|
\fIcurl_easy_perform(3)\fP performs the entire request in a blocking manner
|
|
and returns when done, or if it failed. For non-blocking behavior, see
|
|
\fIcurl_multi_perform(3)\fP.
|
|
|
|
You can do any amount of calls to \fIcurl_easy_perform(3)\fP while using the
|
|
same \fBeasy_handle\fP. 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 \fBeasy_handle\fP. Let the function return first before invoking it
|
|
another time. If you want parallel transfers, you must use several curl
|
|
easy_handles.
|
|
|
|
While the \fBeasy_handle\fP is added to a multi handle, it cannot be used by
|
|
\fIcurl_easy_perform(3)\fP.
|
|
.SH RETURN VALUE
|
|
CURLE_OK (0) means everything was ok, non-zero means an error occurred as
|
|
.I <curl/curl.h>
|
|
defines - see \fIlibcurl-errors(3)\fP. If the \fBCURLOPT_ERRORBUFFER(3)\fP was
|
|
set with \fIcurl_easy_setopt(3)\fP there will be a readable error message in
|
|
the error buffer when non-zero is returned.
