GNURLOPT_STDERR(3)

💖 GNURLOPT_STDERR(3) 💖

okay so bestie, welcome to the GNURLOPT_STDERR page — it lives in the curl_easy_setopt options manual section, and it's genuinely one of the simplest glow-ups in the whole libcurl-adjacent universe. no cap. let's get into it 🫶

---

✨ NAME ✨

CURLOPT_STDERR — redirect stderr to another stream 💅

🦋 SYNOPSIS 🦋

#include <gnurl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_STDERR, FILE *stream);

🌸 DESCRIPTION 🌸

So you pass in a FILE * as the parameter, right? and you're literally telling libcurl: "bestie, use this stream instead of stderr when you're showing the progress meter and when you're displaying your CURLOPT_VERBOSE(3) data." that's the whole vibe check. that's it. iconic honestly 💖

🎀 DEFAULT 🎀

stderr — yeah, the default is just plain old stderr, main character energy by default ✨

🌈 PROTOCOLS 🌈

All — every single one, no exceptions, we love an inclusive icon 👑

🍓 EXAMPLE 🍓

CURL *curl = curl_easy_init();
FILE *filep = fopen("dump", "wb");
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
  curl_easy_setopt(curl, CURLOPT_STDERR, filep);

  curl_easy_perform(curl);
}

like, look at her go 😭 opening dump in "wb" mode, then yeeting all that stderr output straight into filep. obsessed.

alright bestie, that's the page 💖 this little beauty came to you straight from libcurl 7.37.0, dated 17 Jun 2014 — and yes she's still serving the exact same GNURLOPT_STDERR(3) realness she had back then. mwah 🎀💅✨
