DMMP_CONTEXT_LOG_FUNC_SET(3)

💖 NAME 💖

dmmp_context_log_func_set — the little function that lets you set your very own log handler function, bestie. she's here to catch all the tea your code is spilling ✨

---

🌸 SYNOPSIS 🌸

void dmmp_context_log_func_set (struct dmmp_context *ctx, void
(*log_func) (struct dmmp_context *ctx, int priority, const char *file,
int line, const char *func_name, const char *format, va_list args));

---

🎀 ARGUMENTS 🎀

• ctx — a pointer of 'struct dmmp_context'. no cap, if this pointer is NULL, your program will be terminated by assert. like, straight up deleted. gone. 💀 so pls pass a real one.
• log_func — a pointer of the log handler function. if you set this to NULL, all log will be ignored. she's just not listening anymore 🙈

---

🦋 DESCRIPTION 🦋

okay so here's the vibe: this function sets a custom log handler. your handler gets invoked whenever a log message is equal or more important (less value) than the log priority setting — yes bestie, less value means more important, it's giving upside-down logic but that's just how it is, iykyk.

💡 for the full detail usage, go check the manpage libdmmp.h(3). she has the lore. 📖✨

👑 RETURN 👑

void

like, she returns nothing. no value, no drama, just vibes. periodt. 💅
