Detailed Description

Class which handles events on IOService objects.

Usually hook libraries create a local IOService object which handles events related to the respective library. To be able to handle these events, the IOService objects need to be registered on the '[X]_srv_configured' or on 'load' hook points (before the MT settings are applied). This class is not thread safe, so all operations must be done on the main thread, while all other threads are either stopped or paused.

Parameters

io_service The IOService to be registered.
