strnchr(9)

💅 strnchr(9) — the Kernel API Manual page you didn't know you needed

okay bestie, so this is the Kernel API Manual page for strnchr, and it's literally the little function that finds a character inside a string but only looks at the first count characters. no cap, it's giving "search but make it bounded" and honestly? we stan a cautious queen. 🎀

---

✨ SYNOPSIS ✨

char * strnchr (const char *s , size_t count , int c );

like, that's the whole vibe right there. three arguments, one pointer returned. slay. 💅

---

🦋 ARGUMENTS 🦋

• s — the string you're searching through. bestie, this is your haystack. 🔍
• count — how many characters you're actually allowed to look at. not one more, not one less. respect the boundary. ✋
• c — the character you're looking for. the one. the main character of this search. 👑

---

🌸 DESCRIPTION 🌸

so here's the tea: the NUL-terminator is considered part of the string, and you can absolutely search for it. like, it's not off-limits. it's invited to the party too. 🎉 so if you're looking for '\0', go off — strnchr will find it and won't even side-eye you for it. 🫶

fr fr, don't forget that detail. the NUL terminator is valid search bait. iykyk. 💀
