nn::boss::RegisterTask Function

nn::Result RegisterTask(
     Task * pTask,
     TaskPolicy * pPolicy,
     TaskAction * pAction,
     TaskOption * pOption = NULL,
     u8 taskStep = DEFAULT_STEP_ID
);

	Name	Description
in	pTask	Specifies a task by task ID.
in	pPolicy	Specifies a task policy.
in	pAction	Specifies a task action. (Currently, the only related tasks are in the NsaDownloadAction class.)
in	pOption	Specifies task options. (Can be omitted) Note: This parameter is not currently supported because it is used with extended features. Do not specify it.
in	taskStep	Specifies a task step ID. (Can be omitted if there is only one task execution step) Note: This parameter is for a feature extension and is currently not supported. Do not specify it.

Returns the function's execution result. Returns one of the Result values listed below.

Value	Description
Result::IsSuccess	Registration successful.
ResultInvalidTaskId	The pTask argument is NULL. Alternatively, the pTask argument is uninitialized, or the pointer of the task ID specified by pTask is NULL or an empty string.
ResultInvalidPolicy	The pPolicy parameter is NULL.
ResultInvalidAction	The pAction parameter is NULL.
ResultInvalidTaskPriority	The task execution priority specification is out of range. Confirm that it is in the range of TaskPriority.
ResultTaskPermissionOutOfRange	The task permission condition specification is out-of-range. Confirm that it is in the range of TaskPermission.
ResultSchedulingPolicyOutOfRange	The scheduling policy is out of range. Confirm that it is in the range of SchedulingPolicy.
ResultInvalidTaskTargetDuration	The task duration is invalid. (This is for future extensibility.)
ResultActionCodeOutOfRange	The task action code is out of range. Confirm that it is in the range of Action.
ResultInvalidUrl	The URL string pointer is NULL or a zero-length string.
ResultApInfoTypeOutOfRange	The AP information type is out of range. Confirm that it is in the range of ApInfoType.
ResultCfgInfoTypeOutOfRange	The Cfg information type is out of range. Confirm that it is in the range of ApInfoType.
ResultInvalidFilePath	The file path string pointer is NULL or a zero-length string.
ResultInvalidOption	The pOption parameter is uninitialized or the option code is out of range. Confirm that it is in the range of ExecOption.
ResultStorageNotFound	Storage has not been registered for the corresponding application ID.
ResultTaskIdAlreadyExist	A task having the same task ID is already registered.
ResultIpcNotSessionInitialized	The session has not been initialized. This Result is returned if this function is called before the Initialize function. Always call the Initialize function first when using the BOSS library.
A value other than the above	Unexpected error (see boss_Result.h for error details).

Registers a task.

To register tasks, you must prepare instances of the subclass of TaskPolicy class and the TaskAction class (currently only NsaDownloadAction available). See the topic for each class for more information on which attributes must be set.

After you have finished registering a task, you can reuse each of these instances, as necessary, by calling the Initialize function. A task execution instruction can be issued by calling the nn::boss::Task::Start function for a registered task.

　

Common Task Registration Errors

1. If BOSS storage has not been registered when registering an NADL task (ResultStorageNotFound).
Register BOSS storage for NADL task using RegisterStorage.

2. A task with the same task ID is already registered (ResultTaskIdAlreadyExist).
Either use the UnregisterTask function to delete one of the tasks in question, or reuse the task that has already been registered.
