|
2021-03-21 18:18:39 +00:00

|
* - On Windows, function pointers are specific to the current GL context;
|
2021-07-14 21:07:04 +00:00
|
|
|
* this means you need to have created a GL context and made it current
|
|
|
|
* before calling SDL_GL_GetProcAddress(). If you recreate your context or
|
|
|
|
* create a second context, you should assume that any existing function
|
|
|
|
* pointers aren't valid to use with it. This is (currently) a
|
|
|
|
* Windows-specific limitation, and in practice lots of drivers don't suffer
|
|
|
|
* this limitation, but it is still the way the wgl API is documented to
|
|
|
|
* work and you should expect crashes if you don't respect it. Store a copy
|
|
|
|
* of the function pointers that comes and goes with context lifespan.
|
2021-03-21 18:18:39 +00:00
|
|
|
* - On X11, function pointers returned by this function are valid for any
|
2021-07-14 21:07:04 +00:00
|
|
|
* context, and can even be looked up before a context is created at all.
|
|
|
|
* This means that, for at least some common OpenGL implementations, if you
|
|
|
|
* look up a function that doesn't exist, you'll get a non-NULL result that
|
|
|
|
* is _NOT_ safe to call. You must always make sure the function is actually
|
|
|
|
* available for a given GL context before calling it, by checking for the
|
|
|
|
* existence of the appropriate extension with SDL_GL_ExtensionSupported(),
|
|
|
|
* or verifying that the version of OpenGL you're using offers the function
|
|
|
|
* as core functionality.
|
2021-03-21 18:18:39 +00:00
|
|
|
* - Some OpenGL drivers, on all platforms, *will* return NULL if a function
|
2021-07-14 21:07:04 +00:00
|
|
|
* isn't supported, but you can't count on this behavior. Check for
|
|
|
|
* extensions you use, and if you get a NULL anyway, act as if that
|
|
|
|
* extension wasn't available. This is probably a bug in the driver, but you
|
|
|
|
* can code defensively for this scenario anyhow.
|
2021-03-21 18:18:39 +00:00
|
|
|
* - Just because you're on Linux/Unix, don't assume you'll be using X11.

|
2021-03-21 18:18:39 +00:00
