Btw, this webpage https://stackoverflow.com/questions/23847588/how-do-i-use-the-functions-setitimer-and-getitimer says that getitimer and setitimer are obsolete and I should be using timer_gettime() and timer_settime() instead: however, is it possible to handle a virtual clock with these new functions?
