💖 gsasl_check_version(3) — the vibe check for your GNU SASL Library 💖

okay bestie, welcome to section 3 of the gsasl manual, and today we're doing the cutest little API function there ever was. no cap, she's tiny and she's powerful. let's go ✨

✨ NAME ✨

gsasl_check_version — she's an API function, your honor 👑

🦋 SYNOPSIS 🦋

#include <gsasl.h>

const char * gsasl_check_version(const char * req_version);

like, that's it. one include, one function, zero drama 💅

🎀 ARGUMENTS 🎀

  • const char * req_version — the version string you wanna compare against, or NULL if you're feeling feral and just want the version back with no questions asked 🙈

🌸 DESCRIPTION 🌸

So what does she actually do? She checks the GNU SASL Library version. That's the whole job. And she's so good at it.

If you need a suitable string to pass as your req_version, go look at GSASL_VERSION — she's right there waiting for you, iykyk.

Now here's the iconic part: this function is one of the few in the library that can be used without a successful call to gsasl_init(). no init, no problem. she said "I don't need your setup, I'm built different" 💀🔥

Return value: She checks that the version of the library is at minimum the one you gave her as a string in req_version, and then hands you back the actual version string of the library. If that condition isn't met? You get NULL. sorry bestie 😭 but also fair.

And if you pass NULL to this function? No check is done at all — she just returns the version string, periodt. no notes. 🌈
