SDL_SetWindowBordered(3)

💅 SDL_SetWindowBordered 💅

okay bestie, gather round, because we're talking about SDL_SetWindowBordered — that's a function from the SDL3 FUNCTIONS fam, and it's lowkey the glow-up button for your window's edges. ✨

---

🌸 NAME 🌸

SDL_SetWindowBordered — set the border state of a window. yes, that's it. that's the whole job. she does one thing and she does it flawlessly. 💖

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_video.h>

bool SDL_SetWindowBordered(SDL_Window *window, bool bordered);

like... she's short, she's sweet, she takes two args. main character energy honestly. 🎀

---

🦋 DESCRIPTION 🦋

so here's the tea, bestie. this function will add or remove the window's SDL_WINDOW_BORDERLESS flag and add or remove the border from the actual window. so it's not just bookkeeping in the flag, she literally changes the real window too. obsessed. 💅

and if the window's border already matches the state you asked for? it's a no-op. she just shrugs and does nothing. no cap. 🙈

⚠️ huge warning bestie: you can't change the border state of a fullscreen window. like at all. don't even try it, that's not a vibe. 😭

---

🍓 FUNCTION PARAMETERS 🍓

• window — the window of which to change the border state. (yes, that window. your window. the one you're thinking about. 👀)
• bordered — false to remove border, true to add border. binary queen. either you're showing off the edges or you're not. ✨

---

💖 RETURN VALUE 💖

returns true on success or false on failure — and if it fails, bestie, call SDL_GetError() for more information. she's not gonna explain herself, you gotta ask. 😤

---

🧚 THREAD SAFETY 🧚

this function should only be called on the main thread. main thread only. no side quests. no other threads sneaking in. periodt. 👑

---

⭐ AVAILABILITY ⭐

this function is available since SDL 3.2.0. so if you're on something older... bestie. upgrade. 🫶
