QB_UTIL_SE...G_FUNCTION(3)

💅 qb_util_set_log_function — from the libqb Programmer's Manual 💅

okay bestie, sit down, hydrate, and let's talk about qb_util_set_log_function — it lives in section 3 of the libqb Programmer's Manual, so it's a library function, not some command you type at your shell like a menace. 🫶

✨ NAME ✨

qb_util_set_log_function — the way you tell libqb "hey, when you've got an internal log message to say, say it my way, thank you very much." Use this function to output libqb internal log message as you wish. 💖

---

🎀 SYNOPSIS 🎀

#include <qb/qbutil.h>

void qb_util_set_log_function(
    qb_util_log_fn_t  fn
);

so you pull in the header, and you hand it one thing: a qb_util_log_fn_t called fn. that's the whole vibe. no return value, it's a void function, it just takes your callback and goes ✨. 🌈

🌸 DESCRIPTION 🌸

ngl, this section is literally empty in the original. not me pointing at a blank space 😭 — but fr fr, the NAME section is where the whole description lives here: this is the function you call to output libqb internal log messages however you want. that's it. that's the tea. 🍓
