This service call returns the task ID currently in RUNNING state to the area pointed to by p_tskid. If this service call is
issued from a task, the ID number of the issuing task is returned. If this service call is issued from non-task context, the task
ID being executed at that point in time is returned. If there are no tasks currently in an executing state, TSK_NONE is re-
turned.
If this service call is to be issued from task context, use get_tid; if issued from non-task context, use iget_tid.
