STRNCASECMP(3P)

💖 STRNCASECMP 💖

okay bestie, quick lil vibe check before we dive in: this page lives in the POSIX Programmer's Manual, and you're reading the STRNCASECMP(3P) entry. it's a short one but it's giving iconic, trust. 🦋

✨ PROLOG ✨

okay so real talk first, no cap. 📢 this manual page is part of the POSIX Programmer's Manual.

two things you need to know, and I'm saying them with my whole chest:

• the Linux implementation of this interface may differ — like, genuinely, go consult the corresponding Linux manual page for the details on Linux behavior.
• or honestly? the interface may not be implemented on Linux at all. 🙈

so don't come for me if it's not there. check first. periodt. 💅

🌸 NAME 🌸

strncasecmp, strncasecmp_l — case-insensitive string comparisons 👑

like, it compares strings but it does NOT care about your capitalization situation. lowercase, uppercase, chaotic mixed case — it's unbothered. ✨

---

🎀 SYNOPSIS 🎀

okay here's the summoning ritual, get your include in first:

#include <strings.h>

int strncasecmp(const char *s1, const char *s2, size_t n);
int strncasecmp_l(const char *s1, const char *s2,
    size_t n, locale_t locale);

look at those signatures, they ate. 🔥 note the _l version has a whole extra locale_t locale argument because it's fancy like that.

---

🦋 DESCRIPTION 🦋

bestie. the entire description is this:

Refer to strcasecmp().

that's it. that's the whole thing. 😭 it's giving "go ask your other manpage." so literally, if you want the actual deets on how the comparison works, strcasecmp() is your main character — this page is just the n-flavored sibling pointing you over there. go read it, iykyk. 💜
