| IOScreenRegistration |
| Adopted By: | The event system | |
| Declared In: | driverkit/eventProtocols.h |
| Protocol Description |
| Display drivers use the messages in the IOScreenRegistration protocol to register and unregister themselves with the event system. These methods are called by IODisplay in response to an getIntValues:forParameter:count: call that specifies the "IO_Framebuffer_Register" parameter.
You shouldn't need to invoke the methods in this protocol, because they're already invoked automatically by IOFrameBufferDisplay and IOSVGADisplay. |
| Instance Methods |
| registerScreen:bounds:shmem:size: |
| (int)registerScreen:(id)instance |
| bounds:(Bounds *)bounds shmem:(void **)address size:(int *)num |
| Registers instance as a display driver. Returns a token that's used to refer to the display in other calls to the event system. |
| unregisterScreen: |
| (void)unregisterScreen:(int)token |
| Unregisters the instance associated with token as a display driver. |
