💅 SDL_reinterpret_cast 💅

okay bestie, welcome to the SDL3 FUNCTIONS section of the manual, and today's main character is SDL_reinterpret_cast — the macro that handles a reinterpret cast properly whether you're living in C or in C++. yes she does both. she's versatile like that. 🦋

✨ NAME ✨

SDL_reinterpret_cast — handle a Reinterpret Cast properly whether using C or C++.

no cap, that's literally the whole job description. 💖

✨ SYNOPSIS ✨

#include <SDL3/SDL_stdinc.h>

#define SDL_reinterpret_cast(type, expression) reinterpret_cast<type>(expression)  /* or `((type)(expression))` in C */

look at her. one little #define carrying the whole team. 👑

✨ DESCRIPTION ✨

So here's the vibe check: if you're compiled as C++, this macro hands you a proper C++ reinterpret_cast<>. iconic behavior, zero complaints. ✨

If you're compiled as C, this macro just does a normal C-style cast. different language, same energy. 💅

And why do we care? Because it's helpful to avoid compiler warnings in C++. your build log stays clean, your compiler stays quiet, your mental health stays intact. periodt. 🫶

✨ MACRO PARAMETERS ✨

  • type — the type to cast the expression to. yes, that type. the one you want. 🎀
  • expression — the expression to cast to a different type. the thing getting glow-upped. ✨

✨ RETURN VALUE ✨

Returns expression, cast to type. that's it, that's the whole plot twist. 🍓

✨ THREAD SAFETY ✨

It is safe to call this macro from any thread. every thread can have a turn, no fighting, we share in this house. 🧚

✨ AVAILABILITY ✨

This macro is available since SDL 3.2.0. if you're on anything older... bestie. upgrade. 😭

✨ SEE ALSO ✨

the whole cast family, together again. obsessed. 👑

fr fr, if you ever find yourself writing a raw C-style cast inside C++ code and the compiler starts yelling at you, just remember: SDL_reinterpret_cast was right there the whole time. iykyk. 💀
