SDL_strnlen(3)

💖 SDL_strnlen — the vibe check on your string length 💖

okay so bestie, welcome to SDL_strnlen, a lil function from the SDL3 FUNCTIONS fam. It does exactly what strnlen() does, except it doesn't need access to a C runtime, which is lowkey iconic of it.

---

✨ NAME ✨

SDL_strnlen — works exactly like strnlen() but doesn't require access to a C runtime. no cap, that's the whole pitch 🫶

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_stdinc.h>

size_t SDL_strnlen(const char *str, size_t maxlen);

---

🦋 DESCRIPTION 🦋

So what it actually does: it counts up to a maximum of maxlen bytes in str, excluding the null terminator. That's it, that's the job. She's a counter, not a fighter 💅

If you need the length of a UTF-8 string, bestie, consider using SDL_utf8strnlen() instead. different function, different vibe, iykyk.

---

🎀 FUNCTION PARAMETERS 🎀

• str — the null-terminated string you want to read. Must not be NULL — like, genuinely, don't. 🚫
• maxlen — the maximum amount of bytes to count. she stops here, periodt.

---

⭐ RETURN VALUE ⭐

Returns the length (in bytes, excluding the null terminator) of src, but never more than maxlen. yes the page really says src there and not str — not me noticing that 🙈 we simply respect the lore.

---

🔥 THREAD SAFETY 🔥

It is safe to call this function from any thread. go forth and thread it, queen 👑

---

🌈 AVAILABILITY 🌈

This function is available since SDL 3.2.0. if you're on something older, sorry babe 😭
