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