PR_GET_UNALIGN(2const)

✨ PR_GET_UNALIGN(2const) ✨

okay bestie, so this is a page from the Linux man-pages, section 2const (that's the "constants and stuff that go with prctl(2)" corner of the manual, iykyk) 💅 sit down, we're doing unaligned access control bits today and honestly? it's giving lowkey iconic.

🎀 NAME 🎀

PR_GET_UNALIGN — get unaligned access control bits

📚 LIBRARY 📚

Standard C library (libc, -lc) 🫶

🌸 SYNOPSIS 🌸

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

int prctl(PR_GET_UNALIGN, unsigned int *bits);

💖 DESCRIPTION 💖

okay so real talk: this one pulls the unaligned access control bits out for you and drops them in the place that bits is pointing at. that's it. that's the whole function. it looks at where bits points, and the bits land right there. no cap. ✨

🔥 RETURN VALUE 🔥

• on success? 0 gets returned, slay 💅
• on error? -1 gets returned, and errno is set to tell you what went wrong (the drama, tbh)

💀 ERRORS 💀

• EFAULT — bits is an invalid address. 🚫 not a valid place to write, sorry bestie, that pointer is not it.

👑 STANDARDS 👑

Linux. that's the standard. we're a Linux girlie here, periodt. 🐧
