💅 SDL_WINDOWPOS_ISCENTERED 💅

okay bestie, welcome to the SDL_WINDOWPOS_ISCENTERED(3) page from the SDL3 functions manual, and lemme tell you, this one is short and sweet and honestly kinda iconic for it. ✨

🌸 NAME 🌸

SDL_WINDOWPOS_ISCENTERED — it's a macro, and its whole job is testing whether a window position is marked as "centered." that's it. that's the gig. and it ate. 🎀

🦋 SYNOPSIS 🦋

first things first, you gotta pull in the header, no cap:

#include <SDL3/SDL_video.h>

and here's the macro itself, bestie, character for character, don't you dare touch it:

#define SDL_WINDOWPOS_ISCENTERED(X)    \
            (((X)&0xFFFF0000) == SDL_WINDOWPOS_CENTERED_MASK)

see that? it masks off the low bits with 0xFFFF0000 and vibe-checks the rest against SDL_WINDOWPOS_CENTERED_MASK. it's giving bitwise main character energy. 🫶

🌈 MACRO PARAMETERS 🌈

  • X — the window position value. that's the thing you're asking about, and the macro will lowkey tell you if it's centered-coded. 💖

⭐ AVAILABILITY ⭐

this macro has been serving since SDL 3.2.0. so if you're on something older, sorry babe, she's not there yet. 😭
