Hello.
I'm going through the book Posix Programming interface.
When I set the timer timer_t, I set the itimerspec's first expiration to
1, and run the program, the timer works fine. When I set it to 0, it
doesnt work anymore.
Let me show you what I mean:
void itimerspecFromStr(char *interval, struct itimerspec *tsp)
{
tsp->it_value.tv_sec = 1; //<-------------- when its set to one, it works.
tsp->it_value.tv_nsec = 0;
tsp->it_interval.tv_sec = atoi(interval);
tsp->it_interval.tv_nsec = 0;
}
When I set that value to zero, and run the same program, it doesnt work
anymore.
Is that normal?
Thanks in advance.
