(This is the documentation for SDL3, which is under heavy development and the API is changing! SDL2 is the current stable version!)

SDL_EGL_SetAttributeCallbacks

Sets the callbacks for defining custom EGLAttrib arrays for EGL initialization.

Header File

Defined in <SDL3/SDL_video.h>

Syntax

void SDL_EGL_SetAttributeCallbacks(SDL_EGLAttribArrayCallback platformAttribCallback,
                                  SDL_EGLIntArrayCallback surfaceAttribCallback,
                                  SDL_EGLIntArrayCallback contextAttribCallback);

Function Parameters

SDL_EGLAttribArrayCallback	platformAttribCallback	callback for attributes to pass to eglGetPlatformDisplay.
SDL_EGLIntArrayCallback	surfaceAttribCallback	callback for attributes to pass to eglCreateSurface.
SDL_EGLIntArrayCallback	contextAttribCallback	callback for attributes to pass to eglCreateContext.

Remarks

Each callback should return a pointer to an EGL attribute array terminated with EGL_NONE. Callbacks may return NULL pointers to signal an error, which will cause the SDL_CreateWindow process to fail gracefully.

The arrays returned by each callback will be appended to the existing attribute arrays defined by SDL.

NOTE: These callback pointers will be reset after SDL_GL_ResetAttributes.

Version

This function is available since SDL 3.0.0.
