NULL, 3, NULL);

Thanks, good resource. I

have other questions: I have a light intensity project which flash leds respectivaly to light inetnsity like below:

while(1) {
....
if (adc_volt > 220){
led_on_of(1,1);
}else{led_on_of(1,0);led_on_of(2,0);led_on_of(3,0);led_on_of(4,0);}
if (adc_volt > 250){
led_on_of(2,1);
}else{led_on_of(2,0);led_on_of(3,0);led_on_of(4,0);}

...
}

1.) Is it good idea to open new thread for each led_of_of function ?
2.) What is an adventage of use thread instead of just function call ?
3.) Should I delete threads after their job ?
4.) In general when should we use Threads ?

Thanks.
