Modify methods' IL codes on runtime even if they have been JIT-compiled, supports release mode / x64 & x86, and variants of .NET versions, from 2.0 to 4.5.

.TH curl_easy_perform 3 "5 Mar 2001" "libcurl 7.7" "libcurl Manual"
.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.
.SH "SEE ALSO"
.BR curl_easy_init "(3), " curl_easy_setopt "(3), "
