okay bestie, welcome to the POSIX Programmer's Manual, page gethostid(3P). pull up a chair, we're gonna find out who your computer thinks it is 🫶

🌸 PROLOG 🌸

so like, real talk first — this manual page is part of the POSIX Programmer's Manual. the Linux implementation of this interface may differ, so if you're on Linux, go check the corresponding Linux manual page for the deets on Linux behavior. orrrr… the interface might not even be implemented on Linux at all. 🙈 iconic of it, honestly.
