Well, I don't know where exactly to ask this doubt so I'm asking in the newbie section. I was reading about traps and interrupts when I thought of traps as something that cease the control of the OS from the user and interrupts that cease the control yet provide support for multitasking. Am I right in thinking that? In that case, I think we can generate traps using our programs but why would we want to do it anyways? I mean when interrupts are proving better ways of handling the transfer of control, what use would we have for a trap?
