WCSNCMP(3P)

💖 WCSNCMP(3P) — the wide-char glow-up 💖

okay bestie, so this one's from the POSIX Programmer's Manual (yes, the 3P manual, we love a section suffix) 🎀

🚨 PROLOG

This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so like, go consult the corresponding Linux manual page for the tea on Linux behavior 🫖 — or the interface may not be implemented on Linux at all. Not every baddie shows up to every party, iykyk.

✨ 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 🌸

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 — like, no beef, it's giving accidental. 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 (and wide-character codes that follow a null wide-character code are not compared, okay? don't come for me) from the array pointed to by ws1 to the array pointed to by ws2. 💖

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. First difference wins, no cap. 👑

🎀 RETURN VALUE 🎀

Upon successful completion, wcsncmp() shall return an integer:

• greater than 0 if the possibly null-terminated array pointed to by ws1 is greater than the possibly null-terminated array pointed to by ws2 🔥
• equal to 0 if they're equal — matching energy, we love to see it 🌈
• less than 0 if the ws1 array is less than the ws2 array 💜

💀 ERRORS 💀

No errors are defined. She simply does not have problems. Iconic behavior honestly.

The following sections are informative. (aka, the vibes-only sections, not the rules-are-rules sections 🧚)

🍓 EXAMPLES 🍓

None. (Yeah, I know. Nothing to show. We're all just out here trusting the process 🙈)

💜 APPLICATION USAGE 💜

None. (Also nothing. Two sections of pure silence, and honestly? slay.)

⭐ RATIONALE ⭐

None.

🦋 FUTURE DIRECTIONS 🦋

None. The future is bright and this function is staying exactly as she is ✨

mwah, that's the whole page, we ate and left no crumbs 💅✨ This edition came to you from IEEE/The Open Group, dated 2017, filed under WCSNCMP(3P). bye bestie, go compare some wide-character strings responsibly 🌸🎀
