al_get_default_shader_source(3alleg5)

✨ al_get_default_shader_source ✨

okay bestie, welcome to the Allegro 5 API manual, the al_get_default_shader_source(3alleg5) page 💖 this one's short and sweet, so let's get into it.

---

🌸 SYNOPSIS 🌸

#include <allegro5/allegro.h>

char const *al_get_default_shader_source(ALLEGRO_SHADER_PLATFORM platform,
   ALLEGRO_SHADER_TYPE type)

---

🦋 DESCRIPTION 🦋

So this function hands you back a string containing the source code for Allegro's default vertex or pixel shader — whichever one is the right fit for the platform you passed in. Slay. 💅

Now for the tea on ALLEGRO_SHADER_AUTO: if you pass that, it means GLSL gets used when OpenGL is the one doing the rendering, and otherwise it's HLSL. 👑

⚠️ lowkey important: ALLEGRO_SHADER_AUTO requires that there's a current display set on the calling thread. no display, no deal, fr fr.

Also, heads up — this function can return NULL if Allegro was built without support for shaders on the platform you picked. so like, check your return value, bestie, don't just assume. 😭
