|Begin of driver defined context data structure. |
A device context structure is associated with every open device instance. RTDM takes care of its creation and destruction and passes it to the operation handlers when being invoked.
Drivers can attach arbitrary data immediately after the official structure. The size of this data is provided via rtdm_device.context_size during device registration.
