How do I use the new bindings with SDL.zig?

[mstrng]

I have seen the use of the "gl.load" function, but I don't know how to get the required parameters to pass when using SDL.zig. I have seen the other examples with glfw, but I don't understand or know which parameters have to be passed. My project was working fine before, but now it won't run saying that a function isn't bound.

lib/zgl/binding.zig:2722:54: 0x296d3e in createProgram (usg)
    return (function_pointers.glCreateProgram orelse @panic("glCreateProgram was not bound."))();
                                                     ^
lib/zgl/zgl.zig:757:68: 0x263b9c in createProgram (usg)
    const program = @intToEnum(types.Program, binding.createProgram());
                                                                   ^
src/Renderer.zig:48:38: 0x2636a3 in init (usg)
    const program = gl.Program.create();
    ...

In a similar way to the mach-glfw example, you invoke loadExtensions with SDL_GL_GetProcAddress

[mstrng]

Well, the following seems to compile and run, but I don't know if it's the intended way to do it:

fn glGetProcAddress(p: []const u8, proc: [:0]const u8) ?*const anyopaque {
    _ = p;
    return sdl.c.SDL_GL_GetProcAddress(@ptrCast([*c]const u8, proc));
}

    const proc: []const u8 = undefined;
    try gl.loadExtensions(proc, glGetProcAddress);

[ikskuh]

you can just use void for the context parameter:

fn glGetProcAddress(_: void, proc: [:0]const u8) ?*const anyopaque {
    return sdl.c.SDL_GL_GetProcAddress(proc.ptr);
}
try gl.loadExtensions({}, glGetProcAddress);

I think it would be helpful to explain what the function does and maybe document it in the SDL.zig repo?
