NAME
SDL_GL_ExtensionSupported - Check if an OpenGL extension is supported for the current context.
SYNOPSIS
#include <SDL3/SDL_video.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.
