✨ GNURLOPT_XFERINFODATA(3) ✨

okay so bestie, welcome to the GNURLOPT_XFERINFODATA(3) page — it lives in the curl_easy_setopt options manual, and it's lowkey iconic 💅

🎀 NAME 🎀

CURLOPT_XFERINFODATA — a custom pointer that gets passed to the progress callback. That's the whole vibe, no cap.

🌸 SYNOPSIS 🌸

bestie, here's the exact signature — do not touch the punctuation 💖

#include <gnurl/curl.h>

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

🦋 DESCRIPTION 🦋

So you pass in a pointer, and libcurl will leave it completely untouched — like your fave hoodie that nobody else is allowed to borrow 🙈 — and that same pointer gets passed as the first argument in the progress callback set with CURLOPT_XFERINFOFUNCTION(3).

Also, this is an alias for CURLOPT_PROGRESSDATA(3). Slay ✨

💜 DEFAULT 💜

The default value of this parameter is NULL. So if you don't set it, it's NULL, periodt.

🌈 PROTOCOLS 🌈
