  • System Calls System Calls
    System calls We will investigate several issues related to system calls. Read chapter 12 of the book Linux system call categories file management process management error handling note that these categories are loosely defined and much is behind included, e.g. communication. Why? 1 System calls File management system call hierarchy you may not see some topics as part of “file management”, e.g., sockets 2 System calls Process management system call hierarchy 3 System calls Error handling hierarchy 4 Error Handling Anything can fail! System calls are no exception Try to read a file that does not exist! Error number: errno every process contains a global variable errno errno is set to 0 when process is created when error occurs errno is set to a specific code associated with the error cause trying to open file that does not exist sets errno to 2 5 Error Handling error constants are defined in errno.h here are the first few of errno.h on OS X 10.6.4 #define EPERM 1 /* Operation not permitted */ #define ENOENT 2 /* No such file or directory */ #define ESRCH 3 /* No such process */ #define EINTR 4 /* Interrupted system call */ #define EIO 5 /* Input/output error */ #define ENXIO 6 /* Device not configured */ #define E2BIG 7 /* Argument list too long */ #define ENOEXEC 8 /* Exec format error */ #define EBADF 9 /* Bad file descriptor */ #define ECHILD 10 /* No child processes */ #define EDEADLK 11 /* Resource deadlock avoided */ 6 Error Handling common mistake for displaying errno from Linux errno man page: 7 Error Handling Description of the perror () system call.

The OS examines the call parameters The OS performs the requested function The OS saves its state (and call results) The OS returns control of the CPU to the caller Copyright ©: University of Illinois CS 241 Staff 6 Steps for Making a System Call

  • Introduction to PC Operating Systems
    Introduction to PC Operating Systems Operating System Concepts 8th Edition Written by: Abraham Silberschatz, Peter Baer Galvin and Greg Gagne John Wiley & Sons, Inc. ISBN: 978-0-470-12872-5 Chapter 2 Operating-System Structure The design of a new operating system is a major task. It is important that the goals of the system be well defined before the design begins. These goals for the basis for choices among various algorithms and strategies. What can be focused on in designing an operating system • Services that the system provides • The interface that it makes available to users and programmers • Its components and their interconnections Operating-System Services The operating system provides: • An environment for the execution of programs • Certain services to programs and to the users of those programs. Note: (services can differ from one operating system to another) A view of operating system services user and other system programs GUI batch command line user interfaces system calls program I/O file Resource communication accounting execution operations systems allocation error protection detection services and security operating system hardware Operating-System Services Almost all operating systems have a user interface. Types of user interfaces: 1. Command Line Interface (CLI) – method where user enter text commands 2. Batch Interface – commands and directives that controls those commands are within a file and the files are executed 3. Graphical User Interface – works in a windows system using a pointing device to direct I/O, using menus and icons and a keyboard to enter text. Operating-System Services Services Program Execution – the system must be able to load a program into memory and run that program.
