GNURLOPT_DEBUGDATA(3)

📦 version 7.72.0, in nixos 26.05, nixpkgs unstable

🎀 NAME 🎀

okay so this is the GNURLOPT_DEBUGDATA(3) page from the curl_easy_setopt options manual, bestie — and it's giving “tiny but crucial setup detail” energy. It's all about CURLOPT_DEBUGDATA: the custom pointer for your debug callback. 💅

✨ SYNOPSIS ✨

#include <gnurl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DEBUGDATA, void
       *pointer);

💖 DESCRIPTION 💖

You pass in a pointer to literally whatever you want, and that pointer gets passed in to your CURLOPT_DEBUGFUNCTION(3) callback as its last void * argument. 🫶

Here's the iconic detail: libcurl does not use this pointer itself. It is only passed to the callback. That's it. That's the whole vibe. ✨

  • CURLOPT_DEBUGDATA — the custom pointer you're handing over so your debug callback can receive it in its final void * argument; libcurl leaves it alone and only passes it to the callback.

🌸 DEFAULT 🌸

NULL — no pointer, no problem. 🎀

🦋 PROTOCOLS 🦋

All — every protocol, periodt. 🌈

⭐ EXAMPLE ⭐

the example lives right here, and you can copy it exactly:

👑 AVAILABILITY 👑

Always — it's always there for you, bestie. 💜

🔥 RETURN VALUE 🔥

Returns CURLE_OK — slay. 💅
