An additional variable 'next_task' is helpful and clear for those who wants to change something according to the next task. If only 'current_task' is used, it must implicitly assume that the next task is the current task before kernel selects the next one. It is a fault when more than 2 tasks are created, for example: if Task [length of execution] => 1[1T], 2[2T], 3[3T] Task : 1 -> 2 -> 3 -> 1 -> 2 ->3 Length of execution : 1T->2T->1T->2T->3T->1T (<--- which is wrong)
Use
typedef struct {
...
} tcb;
instead of
struct task_c_b {
...
} typedef tcb;
