struct

OpenGL::Loader

Inherits Struct < Value < Object

Loads OpenGL functions dynamically at runtime and returns Proc instances to invoke them. The OpenGL functions are lazy-loaded.

Constants

FUNCTION_COUNT = 657

Constructors

new

Creates the loader. The get_proc_address block is used to retrieve addresses of OpenGL functions. It is given a string that is the name of the OpenGL function to lookup. The block must return a pointer to the function corresponding to the name. If a function is unavailable, the block should return a null pointer.
