In Unix systems the read system call is implemented by the a procedure in the standard library package (libc) which is also called read. Is is essential that both of these have the same name? 2.To a programmer, a system call looks like any other call to a library procedure. Under what circumstances would it be important that a programmer knows which library procedures result in system calls. thanks
