LIBMINICOREDUMPER(7)

💖 LIBMINICOREDUMPER 💖

okay so real talk — this is section 7 of the manual, the minicoredumper manual, and it's about libminicoredumper. it's a whole library bestie. let's get into it ✨

✨ NAME ✨

libminicoredumper — a library for registering application data for dumping with the minicoredumper(8) 🫶

---

🌸 DESCRIPTION 🌸

so libminicoredumper gives you an interface for registering binary and text data so it can get dumped by the minicoredumper(8). literally that's its whole thing. 💅

and the data? it can be dumped into a core(5) file (in case this application crashes 😭), or into separate files for simple access. your choice, your vibe. 🌈

here's the iconic part: if any data is registered for dumping, an anonymous UNIX domain socket is used to send a message to minicoredumper_regd(8), thus registering this application with the minicoredumper(8). no cap. 🎀

then, when some other application crashes, the minicoredumper(8) will dump the registered data from this application as well. the way that works is so clever actually. 👑

this feature allows variable information from multiple applications to be dumped soon after any application crashes. group-chat energy but for crash dumps fr fr. 💀

and to minimize the time between an application crash and the dumping of other registered applications, the minicoredumper(8) uses PTRACE_SEIZE and PTRACE_INTERRUPT to temporarily pause registered applications until all dumping is complete. iconic behaviour tbh ✨
