32 * Public EGL API entrypoints
33 *
34 * Generally, we use the EGLDisplay parameter as a key to lookup the
35 * appropriate device driver handle, then jump though the driver's
36 * dispatch table to handle the function.
37 *
38 * That allows us the option of supporting multiple, simultaneous,
39 * heterogeneous hardware devices in the future.
40 *
41 * The EGLDisplay, EGLConfig, EGLContext and EGLSurface types are
42 * opaque handles. Internal objects are linked to a display to
43 * create the handles.
44 *
45 * For each public API entry point, the opaque handles are looked up
46 * before being dispatched to the drivers. When it fails to look up
47 * a handle, one of
48 *
49 * EGL_BAD_DISPLAY
50 * EGL_BAD_CONFIG
51 * EGL_BAD_CONTEXT
52 * EGL_BAD_SURFACE
53 * EGL_BAD_SCREEN_MESA
54 * EGL_BAD_MODE_MESA
55 *
56 * is generated and the driver function is not called. An
57 * uninitialized EGLDisplay has no driver associated with it. When
58 * such display is detected,
59 *
60 * EGL_NOT_INITIALIZED
61 *
62 * is generated.
63 *
64 * Some of the entry points use current display, context, or surface
65 * implicitly. For such entry points, the implicit objects are also
66 * checked before calling the driver function. Other than the
67 * errors listed above,
68 *
69 * EGL_BAD_CURRENT_SURFACE
70 *
71 * may also be generated.
72 *
73 * Notes on naming conventions:
74 *
75 * eglFooBar - public EGL function
76 * EGL_FOO_BAR - public EGL token
77 * EGLDatatype - public EGL datatype
78 *
79 * _eglFooBar - private EGL function
80 * _EGLDatatype - private EGL datatype, typedef'd struct
81 * _egl_struct - private EGL struct, non-typedef'd
82 *
