/**
|
|
* Public EGL API entrypoints
|
|
*
|
|
* Generally, we use the EGLDisplay parameter as a key to lookup the
|
|
* appropriate device driver handle, then jump though the driver's
|
|
* dispatch table to handle the function.
|
|
*
|
|
* That allows us the option of supporting multiple, simultaneous,
|
|
* heterogeneous hardware devices in the future.
|
|
*
|
|
* The EGLDisplay, EGLConfig, EGLContext and EGLSurface types are
|
|
* opaque handles. Internal objects are linked to a display to
|
|
* create the handles.
|
|
*
|
|
* For each public API entry point, the opaque handles are looked up
|
|
* before being dispatched to the drivers. When it fails to look up
|
|
* a handle, one of
|
|
*
|
|
* EGL_BAD_DISPLAY
|
|
* EGL_BAD_CONFIG
|
|
* EGL_BAD_CONTEXT
|
|
* EGL_BAD_SURFACE
|
|
* EGL_BAD_SCREEN_MESA
|
|
* EGL_BAD_MODE_MESA
|
|
*
|
|
* is generated and the driver function is not called. An
|
|
* uninitialized EGLDisplay has no driver associated with it. When
|
|
* such display is detected,
|
|
*
|
|
* EGL_NOT_INITIALIZED
|
|
*
|
|
* is generated.
|
|
*
|
|
* Some of the entry points use current display, context, or surface
|
|
* implicitly. For such entry points, the implicit objects are also
|
|
* checked before calling the driver function. Other than the
|
|
* errors listed above,
|
|
*
|
|
* EGL_BAD_CURRENT_SURFACE
|
|
*
|
|
* may also be generated.
|
|
*
|
|
* Notes on naming conventions:
|
|
*
|
|
* eglFooBar - public EGL function
|
|
* EGL_FOO_BAR - public EGL token
|
|
* EGLDatatype - public EGL datatype
|
|
*
|
|
* _eglFooBar - private EGL function
|
|
* _EGLDatatype - private EGL datatype, typedef'd struct
|
|
* _egl_struct - private EGL struct, non-typedef'd
|
|
*
