NAME

       waffle_make_current, waffle_get_current_display, waffle_get_current_window,
       waffle_get_current_context - set and get resources current to the thread

SYNOPSIS

       #include <waffle.h>

       bool waffle_make_current(struct waffle_display *display, struct waffle_window *window,
                                struct waffle_context *context);

       struct waffle_display *waffle_get_current_display(void);

       struct waffle_window *waffle_get_current_window(void);

       struct waffle_context *waffle_get_current_context(void);

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

       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.

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.

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.
