✨ NAME ✨

libdrop_ambient — force application started with ambient capabilities to drop them 💅

---

🌸 DESCRIPTION 🌸

so like. imagine an app gets started up with ambient capabilities. this library's whole thing is making that app drop them. that's it. that's the job. iconic behavior honestly.

the way you use it is via LD_PRELOAD, and it forces the application to drop those ambient capabilities. it leaves other capabilities intact — we're not out here wrecking the whole vibe, just the ambient ones. 🎀

you can also link against it and it automatically does the right thing. no cap. no manual labor required.

and here's the best part, the part that makes me feral: you do not need to make any calls into the library 😭✨ because all the work is done in the constructor, which runs before main() is called. so by the time your app even wakes up and starts doing stuff, the ambient caps are already gone. main character energy fr fr 👑

no extra code, no function calls, no nothing. it just does it. periodt.
