PR_GET_FP_MODE(2const)

💖 PR_GET_FP_MODE(2const) 💖

okay bestie, gather round, because this one is tiny but it's giving very specific niche energy and I am obsessed 🎀

This is a page from the man-pages fam, and it's all about PR_GET_FP_MODE — the lil prctl call that asks the kernel "hey, what's my floating point mode rn?" 🌸

---

✨ NAME ✨

PR_GET_FP_MODE — get the floating point mode of the calling process 🦋

---

📚 LIBRARY 📚

Standard C library (libc, -lc) 💅

---

🌈 SYNOPSIS 🌈

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

int prctl(PR_GET_FP_MODE);

no cap, that's the whole vibe check 👑

---

💜 DESCRIPTION 💜

So basically it returns a bit mask that represents the current floating-point mode. That's it. That's the whole function. Short queen behavior 👑

If you wanna know what all those bits mean, go read PR_SET_FP_MODE(2const) — that page has the details, this one is just the "hey, what's it set to?" half of the duo 🫶

---

🔥 RETURN VALUE 🔥

• On success: this call returns the nonnegative value described above ⭐
• On error: -1 is returned, and errno is set to indicate the error 💀

👑 STANDARDS 👑

Linux. MIPS only. (yes bestie, only MIPS, that's not a typo, it's giving exclusive 💅)

🕰️ HISTORY 🕰️
