PR_GET_DUMPABLE(2const)

✨ PR_GET_DUMPABLE ✨ (a 2const moment, bestie)

okay so real talk, this is one of those little pages that rides along with prctl(2) — it's not its own whole syscall, it's a constant you hand to prctl, and honestly? iconic behavior. 💅

---

🎀 NAME 🎀

PR_GET_DUMPABLE — goes and fetches the "dumpable" attribute of the calling process. like, it reads the vibe of your own dumpability. no cap.

---

📚 LIBRARY 📚

Standard C library, aka libc, link it with -lc 🫶

---

🌸 SYNOPSIS 🌸

#include <linux/prctl.h>  /* Definition of PR_* constants */
#include <sys/prctl.h>

int prctl(PR_GET_DUMPABLE);

that's it. that's the whole call. one argument, zero drama. ✨

---

💖 DESCRIPTION 💖

So PR_GET_DUMPABLE returns the current state of the calling process's "dumpable" attribute. that's the whole job. it just reports back what the attribute is set to right now. 🦋

If you wanna know what that attribute means or how to change it, go read PR_SET_DUMPABLE(2const) — that's the sister page and she has the lore. iykyk.

---

🍓 RETURN VALUE 🍓

• On success 💖 — it returns the value described up there ^^ (the current state of the dumpable attribute).
• On error 😭 — -1 comes back, and errno gets set to tell you what went wrong.

---

👑 STANDARDS 👑

Linux. that's it, that's the standard. linux girlies only. 💅
