strchr(9)

💅 strchr(9)

okay so real talk — this is the Kernel API Manual page for strchr, and honestly? it's a short one but it eats. let's get into it bestie 🎀

---

✨ NAME ✨

strchr — find the first occurrence of a character in a string. that's it. that's the whole job. main character energy of string functions ngl 🦋

---

🌸 SYNOPSIS 🌸

char * strchr (const char *s , int c );

look at that signature. so clean. so iconic. const char *s goes in, int c goes in, char * comes out. chef's kiss 🔥

---

💖 ARGUMENTS 💖

• s — the string you're searching through, bestie. the whole haystack. 🌾
• c — the character you're hunting for. the needle. the one. 💅

---

👑 DESCRIPTION 👑

here's the little detail that makes everybody go "wait, what" 🙈 — the NUL-terminator is considered part of the string, and you can search for it. no cap. that trailing zero is not exempt, it's a full member of the string, it pays rent, it gets searched. ✨

so yeah, if you go looking for '\0', strchr will happily find it for you. the end of the string is not off-limits. 🫶
