okay bestie, real talk before we get into it 💖 this page is part of the POSIX Programmer's Manual. But here's the tea: the Linux implementation of this interface may be different from what's written here — so pls go consult the corresponding Linux manual page for the deets on Linux behavior. Also possible? The interface just… isn't implemented on Linux at all. 🙈 vibe check accordingly.
