WCSNLEN(3POSIX)

✨ WCSNLEN(3POSIX) ✨

okay bestie, gather round, because today we're learning about wcsnlen — and I promise it's shorter than your ex's attention span. this one lives in the POSIX Programmer's Manual, section 3, and it's giving "tiny page, big feelings." 🦋

🌸 PROLOG 🌸

so like, before we even get into it — this manual page is part of the POSIX Programmer's Manual, okay? which means:

• the Linux implementation of this interface may differ — so if you're on Linux, pls pls pls go consult the corresponding Linux manual page for the details of Linux behavior 💅
• or, plot twist, the interface may not be implemented on Linux at all. 💀 no cap.

basically: POSIX says one thing, your distro might say another. vibe check your platform first, bestie.

two args, one size_t return, zero drama. 🎀

🌈 DESCRIPTION 🌈

...yeah that's literally it. the whole description. she said "go read wcslen(), I'm not repeating myself." 😭
