WCSNCMP(3POSIX)

📦 version 2017a, in debian bookworm, debian trixie, ubuntu jammy, ubuntu noble, ubuntu resolute, ubuntu stonking

🌸 PROLOG 🌸

okay bestie, real talk before we even start: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (so pls consult the corresponding Linux manual page for the deets on Linux behavior), or honestly the interface may just not be implemented on Linux at all. 💀

✨ NAME ✨

wcsncmp — compare part of two wide-character strings 🦋

🎀 SYNOPSIS 🎀

#include <wchar.h>

int wcsncmp(const wchar_t *ws1, const wchar_t *ws2, size_t n);

💖 DESCRIPTION 💖

So the functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional — nobody's trying to start drama. This volume of POSIX.1-2017 defers to the ISO C standard. periodt.

The wcsncmp() function shall compare not more than n wide-character codes from the array pointed to by ws1 to the array pointed to by ws2. And listen — wide-character codes that follow a null wide-character code are not compared. like, they're off the guest list. 🚫

The sign of a non-zero return value shall be determined by the sign of the difference between the values of the first pair of wide-character codes that differ in the objects being compared. it's giving "first disagreement wins." 👑

🌈 RETURN VALUE 🌈

Upon successful completion, wcsncmp() shall return an integer greater than, equal to, or less than 0, if the possibly null-terminated array pointed to by ws1 is greater than, equal to, or less than the possibly null-terminated array pointed to by ws2, respectively. three moods, three outcomes, slay. 💅
