[LITMUS^RT] A little confused on struct subtask subtasks[0]

[Hang Su]

Hi all:

I am reading source code about P-fair scheduling algorithm under
/litmus/sched_pfair.c.* struct* subtask subtasks[0] is declared in
*struct*pfair_param. From definition of function dump_subtasks(struct
task_struct*t), subtasks is like a pointer to struct subtask or the name of
a struct subtask array. But why it is declared as a struct subtask array
with zero element ? is it as the same meaning as a pointer to struct
subtask ?


Thanks.
