Doing this, I also obtain the pid of new process: this one enters in a loop as shown below: while (var == 0) { kproc_suspend_loop(procp); ..... tsleep(procp, PUSER, "procslp", hz); } kthread_exit(0); On unloading this module, I set to 1 'var' and let the thread exits. I hope this the right way to do it. Thanx to everyone, guy :-) Ferruccio PS: oohh my english......
