GNURLINFO_HEADER_SIZE(3)

💖 NAME 💖

okay so this is the page for GNURLINFO_HEADER_SIZE(3), and the manual name is curl_easy_getinfo options 🫶 The NAME itself is CURLINFO_HEADER_SIZE — get size of retrieved headers. Not me noticing the page header and the NAME don’t match exactly 😭 that’s just how it’s written, bestie 💅

✨ SYNOPSIS ✨

#include <gnurl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_HEADER_SIZE, long
*sizep);

---

🦋 DESCRIPTION 🦋

Pass a pointer to a long to receive the total size of all the headers received. Measured in number of bytes, no cap 💖
