curl_easy_perform - Perform a file transfer
#include <curl/curl.h> CURLcode curl_easy_perform(CURL *handle);
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 handle 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 curl_easy_setopt 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.
0 means everything was ok, non-zero means an error occurred as <curl/curl.h> defines. If the CURLOPT_ERROR- BUFFER was set with curl_easy_setopt there will be a read- able error message in the error buffer when non-zero is returned.
Surely there are some, you tell me!
