SDL_LockProperties(3)

💖 SDL_LockProperties(3) 💖

okay bestie, welcome to the SDL3 FUNCTIONS section of the manual, and today's main character is SDL_LockProperties — she's a whole vibe and she's about to keep your properties from getting absolutely bodied by other threads. let's get into it ✨

---

🎀 NAME 🎀

SDL_LockProperties — lock a group of properties, periodt.

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_properties.h>

bool SDL_LockProperties(SDL_PropertiesID props);

---

🦋 DESCRIPTION 🦋

so basically, this function grabs a multi-threaded lock for these properties. while you're holding it, any other thread that tries to lock these same properties is just gonna wait — standing outside the club, no entry, until you unlock them. 😭

⚠️ real talk: properties must be unlocked before they are destroyed. do not skip that step, i am begging.

here's the thing tho — the lock is automatically taken when setting individual properties. so this function isn't something you need for every lil' property write. you only reach for it when you wanna:

• set several properties atomically (all at once, no interlopers, no gaps) 🔥
• guarantee that properties you're querying aren't freed in another thread while you're still looking at them 💀

that's it. that's the whole job. she's niche but she serves. 👑

---

💅 FUNCTION PARAMETERS 💅

• props — the properties to lock. that's the one. the whole squad.

---

⭐ RETURN VALUE ⭐

Returns true on success, or false on failure — and if it fails, call SDL_GetError() for more info, because she will not elaborate unless you ask. 🙈

---

🧚 THREAD SAFETY 🧚

It is safe to call this function from any thread. no cap. every thread is invited to this party. 🌈

---

🍓 AVAILABILITY 🍓

This function has been available since SDL 3.2.0. she's not new-new, but she's not ancient either. iykyk. 💜

mwah 💋 that's the whole page. this one's from the Simple Directmedia Layer girlies, SDL 3.4.18 era — stay locked, stay atomic, and always unlock before you destroy. bye bestie!! 👑✨
