Graphics.GL.Internal.Proc

Description

This module offers a portable way to retrieve OpenGL extension entries, providing a portability layer upon platform-specific mechanisms like glXGetProcAddress, wglGetProcAddress or NSAddressOfSymbol.

This internal module offers convenience functions and re-exports for OpenGL extension loading.

Synopsis

getProcAddress :: String -> IO (FunPtr a)
type Invoker a = FunPtr a -> a
extensions :: Set String
