WCSNLEN(3P)

✨ PROLOG ✨

okay bestie, before we even get into it — this page is part of the POSIX Programmer's Manual, and that's a whole thing you need to know. The Linux implementation of this interface might lowkey differ from what POSIX says (so fr fr, go check the corresponding Linux manual page for the details on how Linux actually behaves), or honestly?? the interface might not even be implemented on Linux at all. 💀

🌸 NAME 🌸

wcsnlen — get length of a fixed-sized wide-character string

like... it counts how long your wide-char string is, but only up to a cap. main character behavior honestly 👑

🦋 SYNOPSIS 🦋

#include <wchar.h>

size_t wcsnlen(const wchar_t *ws, size_t maxlen);

🎀 DESCRIPTION 🎀

so this is the vibe: refer to wcslen(). that's it. that's the whole description. go read wcslen() bestie, it's giving "see also" energy and I respect it 🙈
