Hi, Do every system call have a wrapper, which runs in user space and copies the system call number in the register and then switches the CPU mode to kernel mode ? Please explain. Also when is the kernel stack for a process created ? Is it when the process is created or when the process comes to the kernel mode on invoking a system call ?
