NAME

       SDL_GL_ExtensionSupported - Check if an OpenGL extension is supported for the current context.

HEADER FILE

       Defined in SDL3/SDL_video.h

SYNOPSIS

       #include "SDL3/SDL.h"

       bool SDL_GL_ExtensionSupported(const char *extension);

DESCRIPTION

       This  function operates on the current GL context; you must have created a context and it must be current
       before calling this function. Do not assume that all contexts you  create  will  have  the  same  set  of
       extensions available, or that recreating an existing context will offer the same extensions again.

       While  it's probably not a massive overhead, this function is not an O(1) operation. Check the extensions
       you care about after creating the GL context and save that information somewhere instead of  calling  the
       function every time you need to know.

FUNCTION PARAMETERS

       extension
              the name of the extension to check.

RETURN VALUE

       Returns true if the extension is supported, false otherwise.

THREAD SAFETY

       This function should only be called on the main thread.

AVAILABILITY

       This function is available since SDL 3.2.0.
