Hi! In a system that has full memory protection, what are the way that allow user application to communicate with function inside the OS??? Thanks
You do it with system calls. Basically a system call is a "software interrupt" that get fired off from a user process, which is intercepted by the kernel of the OS to do work on behalf of the user. What OS? Google[^]
