Connecting a Surface to a Screen

You must use an EGLStream to connect a surface (i.e., a stream surface) to a screen. The surface is the stream producer, and the screen is the stream consumer.

• eglGetPlatformDisplayEXT returns an EGLDisplay handle belonging to a screen as specified by platform argument in the function call.
• eglMakeCurrent attaches an EGL rendering context to draw and read an EGL surface. It also binds a context and a surface to the current rendering thread.
• Steps 6 through 9 in Creating a Stream Surface are required for connecting a stream surface to a screen.
• eglGetPlatformDisplayEXT returns a handle to screen.
• eglMakeCurrent binds the handle to the current context and surface.
