Detailed Description

Define types shared by the real-time scheduling and event services.

These types are defined in a separate module to decouple the real-time event services from the scheduling service interface (and implementation!)

Typedef Documentation

typedef long RtecBase::handle_t

Provide a fast, low-footprint identifier for RT_Infos.

The Event and Scheduling Service need to communicate information about RT_Infos (descriptions about the scheduling properties of a simple operation). On a centralized application one would use pointers for such a task, but obviously that does not work on a distributed system. It is tempting to use object references to identify each RT_Info, but that does not work either: first the contents of the RT_Info must be transmitted between applications, and object references are not good identifiers (due to the semantics of _is_equivalent())

The handle_t type is used to generate unique identifiers on the scheduling service, the Event Service can then refer to any RT_Info using either their name or the quicker handle_t.

typedef long RtecBase::OS_Priority

Helper typedef to define the OS priority.

typedef long RtecBase::Preemption_Priority_t

Helper typedef to define the OS-independent priority.

typedef long RtecBase::Preemption_Subpriority_t

Helper typedef to define the OS-independent sub-priority.
