NAME

       SDL_HINT_OPENGL_ES_DRIVER - A variable controlling what driver to use for OpenGL ES contexts.

HEADER FILE

       Defined in SDL3/SDL_hints.h

SYNOPSIS

       #include "SDL3/SDL.h"

       #define SDL_HINT_OPENGL_ES_DRIVER SDL_OPENGL_ES_DRIVER"

DESCRIPTION

       On some platforms, currently Windows and X11, OpenGL drivers may support creating contexts with an OpenGL
       ES  profile.  By default SDL uses these profiles, when available, otherwise it attempts to load an OpenGL
       ES library, e.g. that provided by the ANGLE project. This variable  controls  whether  SDL  follows  this
       default behaviour or will always load an OpenGL ES library.

       Circumstances  where  this is useful include - Testing an app with a particular OpenGL ES implementation,
       e.g ANGLE, or emulator, e.g. those from ARM, Imagination or Qualcomm.  -  Resolving  OpenGL  ES  function
       addresses  at  link  time by linking with the OpenGL ES library instead of querying them at run time with
       SDL_GL_GetProcAddress ().

       Caution: for an application to work with the default behaviour across different OpenGL  drivers  it  must
       query the OpenGL ES function addresses at run time using SDL_GL_GetProcAddress ().

       This variable is ignored on most platforms because OpenGL ES is native or not supported.

       The variable can be set to the following values:

       • "0": Use ES profile of OpenGL, if available. (default)

       • "1": Load OpenGL ES library using the default library names.

       This hint should be set before SDL is initialized.

AVAILABILITY

       This hint is available since SDL 3.2.0.
