Member Function Documentation

CMachine::bit32 PikeAero::CTaskSupervisor::fault

(

)

[virtual]

The CTaskScheduler will call the fault() method when a fault code was returned by any of the task's other methods.

Reimplemented from PikeAero::ITask.

Definition at line 95 of file ctasksupervisor.cpp.

{
    return 0;
}

CMachine::bit32 PikeAero::CTaskSupervisor::init

(

)

[virtual]

called exactly once. perform task initialization such as initializing private variable. other tasks are not guaranteed so do not interract with other tasks at this stage.

Returns:

0 on success.

bool PikeAero::CTaskSupervisor::iowait

(

)

[virtual]

The CTaskScheduler::iowait() method will call the task's iowait method periodically to test if the task is still in an I/O wait state.

Returns:

true if still waiting on I/O, false otherwise.
