## Description

`waffle_make_current()`

  Bind the given window and context for rendering on the current thread. window and context must both have been created on the given display. To unbind the current context without binding a new one, set window and context to `NULL`.

  This function is analogous to `glXMakeCurrent` 3, `eglMakeCurrent` 3, and `[NSOpenGLContext makeCurrentContext]`.

`waffle_get_current_display()`

  Get the display bound to the current thread, as previously bound by `waffle_make_current()`. If no display is bound, then return NULL.

  This function is analogous to `glXGetCurrentDisplay` 3 and `eglGetCurrentDisplay` 3.

`waffle_get_current_window()`

  Get the window bound to the current thread, as previously bound by `waffle_make_current()`. If no window is bound, then return NULL.

  This function is analogous to `glXGetCurrentDrawable` 3 and `eglGetCurrentSurface` 3.

`waffle_get_current_context()`

  Get the context bound to the current thread, as previously bound by `waffle_make_current()`. If no context is bound, then return NULL.

  This function is analogous to `glXGetCurrentContext` 3 and `eglGetCurrentContext` 3.

## Return Value

## Errors

No errors are specific to any functions listed in this manual page.

## Bugs

Mixing calls to `waffle_make_current()` and the native platform's `MakeCurrent()` on the same thread do not interact well. After calling the native platform's `MakeCurrent()`, future Waffle function calls on the same thread are likely to behave incorrectly.
