LOC_SET_LOG_FN(3)

💅 LOC_SET_LOG_FN(3) 💅

ok so we're in the libloc manual, section 3 (library calls, iykyk), and today's main character is loc_set_log_fn. she's tiny, she's iconic, she's gonna make your app's logs actually show up. let's go 🫶

✨ NAME ✨

loc_set_log_fn — sets the log callback function 💖

---

🌸 SYNOPSIS 🌸

#include <libloc/libloc.h>

void loc_set_log_fn(struct loc_ctx* ctx, void (*log_fn)(struct loc_ctx*
ctx, int priority, const char* file, int line, const char* fn, const
char* format, va_list args)

---

🦋 DESCRIPTION 🦋

okay bestie, listen: libloc doesn't wanna be that friend who just prints stuff to stderr without asking. instead it lets you plug in your own logging system — the calling application's logging system, to be exact — by setting this callback. so like, it's giving "you do you, I'll just hand you the messages." 🎀

the callback is the log_fn you pass in, and it'll be called once for each log message, according to the configured log level. so no spam, no surprises — you get exactly the messages that match whatever log level is set. periodt. ✨
