The destructor of this object also deletes the task - object. The last status code should be checked after construction to - see if the create completed successfully. - - The second constructor connects to an existing task object. The last - status code should be checked after construction to see if the - task existed. - - The third constructor is a copy constructor. Connects to an existing - object which is in scope. - - The RTEMS id is set to self in the default construction. - - The creation of the task object can be defered until after - construction. This allows for static task objects to be created. - - RTEMS should be initialised before static constructors run, how-ever - threads will will not. You need to watch the start-order. - - A task object can change state from an owner of a task to being - connected to a task. - - Task objects connected to another task do not receive notification - when the task connected to changes state. - - The sleep methods operate on the current thread not the task - reference by this object. - - Mode control is through the rtemsTaskMode class. - - The rtemsTask class reserved notepad register 31. - - ------------------------------------------------------------------------ */ - -#if !defined(_rtemsTask_h_) -#define _rtemsTask_h_ - -#include <rtems++/rtemsStatusCode.h> - -/* ---- - rtemsTask -*/ - -class rtemsTask - : public rtemsStatusCode -{ -public: - enum FloatingPoint { fpoff = RTEMS_NO_FLOATING_POINT, - fpon = RTEMS_FLOATING_POINT }; - enum Scope { local = RTEMS_LOCAL, - global = RTEMS_GLOBAL }; - - // only the first 4 characters of the name are taken - - // creates a task - rtemsTask(const char* name, - const rtems_task_priority initial_priority, - const rtems_unsigned32 stack_size, - const rtems_mode preemption = RTEMS_NO_PREEMPT, - const rtems_mode timeslice = RTEMS_NO_TIMESLICE, - const rtems_mode asr = RTEMS_NO_ASR, - const rtems_interrupt_level interrupt_level = 0, - const FloatingPoint floating_point = fpoff, - const Scope scope = local); - - // connects to a task - rtemsTask(const char *name, const rtems_unsigned32 node = RTEMS_SEARCH_ALL_NODES); - - // copy and default constructors - rtemsTask(const rtemsTask& task); - rtemsTask(); - - // only the creator's destructor will delete the actual object - virtual ~rtemsTask(); - - // create or destroy (delete) the task - virtual const rtems_status_code create(const char* name, - const rtems_task_priority initial_priority, - const rtems_unsigned32 stack_size, - const rtems_mode preemption = RTEMS_NO_PREEMPT, - const rtems_mode timeslice = RTEMS_NO_TIMESLICE, - const rtems_mode asr = RTEMS_NO_ASR, - const rtems_interrupt_level interrupt_level = 0, - const FloatingPoint floating_point = fpoff, - const Scope scope = local); - virtual const rtems_status_code destroy(); - - // connect to an existing task object, will not be the owner - const rtemsTask& operator=(const rtemsTask& task); - virtual const rtems_status_code connect(const char *name, - const rtems_unsigned32 node = RTEMS_SEARCH_ALL_NODES); - - // run control - virtual const rtems_status_code start(const rtems_task_argument argument); - virtual const rtems_status_code restart(const rtems_task_argument argument); - virtual const rtems_status_code suspend(); - virtual const rtems_status_code resume(); - - // sleep control, the timeout is in micro-seconds - virtual const rtems_status_code wake_after(const rtems_interval micro_secs); - virtual const rtems_status_code wake_when(const rtems_time_of_day& tod); - - // priority control - const rtems_status_code get_priority(rtems_task_priority& priority); - const rtems_status_code set_priority(const rtems_task_priority priority); - const rtems_status_code set_priority(const rtems_task_priority priority, - rtems_task_priority& old_priority); - - // notepad control - const rtems_status_code get_note(const rtems_unsigned32 notepad, - rtems_unsigned32& note); - const rtems_status_code set_note(const rtems_unsigned32 notepad, - const rtems_unsigned32 note); - - // object id, and name - const rtems_id id_is() const { return id; } - const rtems_name name_is() const { return name; } - const char *name_string() const { return name_str; } - -protected: - - // task entry point - virtual void body(rtems_task_argument argument); - -private: - - // make the object to point to RTEMS_SELF - void make_self(); - - // task name - rtems_name name; - char name_str[5]; - - // owner, true if this object owns the task - // will delete the task when it destructs - bool owner; - - // the rtems id, object handle - rtems_id id; - - // the argument for the task, this class uses the actual argument - // passed to RTEMS - rtems_task_argument argument; - - // common entry point to the task - static rtems_task origin(rtems_task_argument argument); -}; - -#endif // _rtemsTask_h_ - |
