[okl4-developer] okl4 system call or API about "delay" and "interrupt"

[kashin Lin]

Hi,

thanks for your reply.

the reason of the need for delay is that :
i want to add some milliseconds delay between contiguous hardware
configuration instruction.
so maybe it's no need to use this powerful method  such as timer.
so are there any alternative way to achieve this goal?
p.s. where are those examples use timer server i can refer to?
       ( i want to learn how to use timer too )



another questions for register irq handler:
if i want to use function_A as irq #B's handler

       thread_ref_t thrd;
       thrd = thread_create_simple( function_A, NULL, 100 );
       hardware_register_interrupt( thread_l4tid(thrd), B );

is the right way to register it?
