UXPRG03

DATES:

1. Getting Started
   • Become familiar with the UNIX tools; open the IDE and code a simple program.
2. UNIX Facilities
   • Using system calls, retrieve the following information: 1- The real user-ID. 2- Group-ID. 3- Effective user-ID. 4- Effective group-ID. 5- Process-ID. 6- The parent process-ID.
3. External Interfaces
   • Dynamically invoke routines in an external library; invoke the two routines provided by the instructor.
4. Sockets
   • Create a TCP socket stream and bind to the stream.
   • Create a client and server program which passes some information to the server, performs simple calculations and returns the results.
5. Streams
   • Introduce the basic Stream I/O library and code sequential I/O processing programs.
   • Using streams and the Standard I/O library, copy one file to another.
6. Client/Server Programming
   • Create a point-to-point communication stream.
   • Code a server that converts all the strings into proper case strings.
7. Pipes
   • Continue with the previous exercise; however this time use named pipes instead of a TCP stream.
   • Display a file by piping into a PAGER program.
8. Processes
   • Become familiar with access process information and learn its architecture.
   • Print current process resource limits: 1- Invoke a process and determine if it is still running. 2- Kill the process and determine if it is running.
9. System V IPC
   • Create an area of shared memory; then code a subsystem that will share application data with the UNIX System V IPC mechanisms.
10. Signals
    • Use a signal to indicate that a task has completed.
    • Print the signal mask for current process; then call a blocking read with a timeout using longjmp.
11. Semaphores
    • Code a program to create a semaphore by using semget; then query the value of the semaphore and take actions based on the value.
12. Message Queues
    • Create and connect to a message queue; then: 1- Create a key and send some data to the queue. 2- Code a routine to receive the data and another routine to destroy the data.
13. Shared Memory
    • Create a program which can access shared memory.
    • Code a client and server program that passes data back and forth; handle the race condition.
14. I/O
    • Create efficient I/O routines.
    • Code a routine to perform large non-blocking writes; then code a client and server program that passes data back and forth.
15. Files and Devices
    • Use the C function `ioctl' (I/O control) for sending special control commands to a device.
16. Memory Management
    • Create a file using memory mapped I/O; then read and write to the file.
17. File and Record Locking
    • Perform locking and lock detection.
    • Create a program which determines the presence of a deadlock situation by testing if a file region is locked by another process.
    • The program should also resolve the deadlock problem.
