A microkernel is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system (OS). These mechanisms include low-level address space management, thread management, and inter-process communication (IPC).

NAME
curl_easy_perform - Perform a file transfer SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_perform(CURL *handle); DESCRIPTION
This function is called after the init and all the curl_easy_setopt(3) 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. You can do any amount of calls to curl_easy_perform(3) 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 curl_easy_setopt(3) 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. RETURN VALUE
0 means everything was ok, non-zero means an error occurred as <curl/curl.h> defines. If the CURLOPT_ERRORBUFFER was set with curl_easy_setopt there will be a readable error message in the error buffer when non-zero is returned. SEE ALSO
