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).
Functions whose return type is bool return true on success and false on failure. Functions whose return
type is a pointer return NULL on failure. Use
waffle_error_get_info(3) to get
information about any errors.
See waffle_error(3) for the complete list of waffle's error codes.
No errors are specific to any functions listed in this manual page.
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.
