2 * Public EGL API entrypoints
4 * Generally, we use the EGLDisplay parameter as a key to lookup the
5 * appropriate device driver handle, then jump though the driver's
6 * dispatch table to handle the function.
8 * That allows us the option of supporting multiple, simultaneous,
9 * heterogeneous hardware devices in the future.
11 * The EGLDisplay, EGLConfig, EGLContext and EGLSurface types are
12 * opaque handles implemented with 32-bit unsigned integers.
13 * It's up to the driver function or fallback function to look up the
14 * handle and get an object.
15 * By using opaque handles, we leave open the possibility of having
16 * indirect rendering in the future, like GLX.
19 * Notes on naming conventions:
21 * eglFooBar - public EGL function
22 * EGL_FOO_BAR - public EGL token
23 * EGLDatatype - public EGL datatype
25 * _eglFooBar - private EGL function
26 * _EGLDatatype - private EGL datatype, typedef'd struct
27 * _egl_struct - private EGL struct, non-typedef'd
