SDL_EGLAttribArrayCallback3type
Egl platform attribute initialization callback.
Usage
#include "SDL3/SDL.h"
typedef SDL_EGLAttrib *(SDLCALL *SDL_EGLAttribArrayCallback)(void *userdata);
Header file
Defined in SDL3/SDL_video.h
Overview
This is called when SDL is attempting to create an EGL context, to let the app add extra attributes to its eglGetPlatformDisplay() call.
The callback should return a pointer to an EGL attribute array terminated with EGL_NONE . If this function returns NULL, the
SDL_CreateWindow
process will fail gracefully.
The returned pointer should be allocated with SDL_malloc () and will be passed to SDL_free ().
The arrays returned by each callback will be appended to the existing attribute arrays defined by SDL.
Function parameters
- userdata
-
an app-controlled pointer that is passed to the callback.
Return value
Returns a newly-allocated array of attributes, terminated with EGL_NONE .
