gnurl_easy_perform(3)

okay so bestie, welcome to the libgnurl Manual page for gnurl_easy_perform(3) — yes, the title is right there, but we're doing it cute instead of a boring header line 💅

✨ NAME ✨

• curl_easy_perform — perform a blocking file transfer

🦋 SYNOPSIS 🦋

#include <gnurl/curl.h>

CURLcode curl_easy_perform(CURL *easy_handle);

💖 DESCRIPTION 💖

okay so here's the vibe: call this function after curl_easy_init(3) and after all your curl_easy_setopt(3) calls are made. It will perform the transfer as described in the options. And it must be called with the same easy_handle as input that the curl_easy_init(3) call returned, no substitutions, iykyk.

curl_easy_perform(3) performs the entire request in a blocking manner and returns when it's done, or if it failed. If you want non-blocking behavior, go see curl_multi_perform(3).

You can do any amount of calls to curl_easy_perform(3) while using the same easy_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.

🚨 serious bestie warning: you must never call this function simultaneously from two places using the same easy_handle. Let the function return first before invoking it another time. If you want parallel transfers, you must use several curl easy_handles.

Also, while the easy_handle is added to a multi handle, it cannot be used by curl_easy_perform(3). periodt 💀

🌸 RETURN VALUE 🌸

CURLE_OK (0) means everything was ok. Non-zero means an error occurred as <gnurl/curl.h> defines — see libcurl-errors(3). If the CURLOPT_ERRORBUFFER(3) was set with curl_easy_setopt(3), there will be a readable error message in the error buffer when non-zero is returned.

🎀 EXAMPLE 🎀

CURL *curl = curl_easy_init();
if(curl) {
  CURLcode res;
  curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
  res = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
}
