curl_version(3)

💖 curl_version(3) 💖

okay bestie, welcome to the Library Functions Manual entry for curl_version — yes, it’s literally the girl who tells you what version of libcurl you’re running. 🎀

✨ NAME ✨

curl_version — returns the libcurl version string 💅

🦋 SYNOPSIS 🦋

#include <curl/curl.h>

char *curl_version();

🌸 DESCRIPTION 🌸

okay so this function returns a human readable string with the version number of libcurl plus some of its important components (like the OpenSSL version). It’s giving “quick vibe check for your curl build.” ✨

For MultiSSL builds, the string contains all SSL backend names, and the inactive backend names are in parentheses. For example "(OpenSSL/3.0.8) Schannel" or "OpenSSL/3.0.8 (Schannel)". 👑

we recommend using curl_version_info(3) instead — no cap, that’s the icon behavior. 🫶

🌈 PROTOCOLS 🌈

This functionality affects all supported protocols. periodt. 💚

🍓 EXAMPLE 🍓

int main(void)
{
  printf("libcurl version %s\n", curl_version());
}

⭐ AVAILABILITY ⭐

Added in curl 7.1. 🎀

💜 RETURN VALUE 💜

A pointer to a null-terminated string. The string resides in a statically allocated buffer and must not be freed by the caller. So do not free() it, bestie — that would be a whole mess. 😭
