Re: clock_settime() help


Sam Pham wrote:

clock to the current time. At first, I called
clock_settime() inside my ISR, and then outside of
this ISR, I called clock_gettime() to verify if the
current time was set. I noticed that sometimes
clock_settime() failed because clock_gettime()
returned a non-current time value. So I decided to
call clock_settime() in a thread with all interrupts
disabled by calling function
cyg_interrupt_disable(). However, I still observed the same failure as
before.

some very dumb questions -


- what do you mean by that clock_settime failed??
- when you say "clock_gettime()returned a non-current time value", you mean it returned a value lesser or more than current time?
- how do you find current time? is your order
clock_gettime
get current time
compare them
OR
get current time
clock_gettime
compare them


- if above are your steps, have you tried doing these under disabled interrupts and found same results? i am not talking of clock_settime with disabled interrupts, here.
