GETCHAR_UNLOCKED(3P)

🌸 PROLOG 🌸

okay bestie, quick vibe check before we even start: this page is part of the POSIX Programmer's Manual (yes, the POSIX Programmer's Manual — we're in getchar_unlocked(3P) territory, section 3P, the P is for POSIX, iykyk). But here's the tea: the Linux implementation of this interface may differ, so consult the corresponding Linux manual page for the details on Linux behavior. OR — plot twist — the interface might not even be implemented on Linux at all. 🙈 So like, don't come for me if it's not there.
