pthread_cond_timedwait returning immediately

Question

I\'m having a strange problem. I have the following code:

    dbg(\"condwait: timeout = %d, %d\\n\", 
        abs_timeout->tv_sec, abs_timeout->tv_nsec);
          


        

Answer 1

As already in other answers mentioned you have to use the absolute time. Since C11 you can use timespec_get().

struct timespec time;
timespec_get(&time, TIME_UTC);
time.tv_sec += 5;

pthread_cond_timedwait(&cond, &mutex, &time);
