We'll be working some in a Unix environment this semester, at least through process creation. So this is a very simple get-started assignment. Create a Unix or Linux program that runs and prints out its process id, its parent process id, its owner user id and its owner group id. Like this:

[bennet@m-mcc-csc-01456 asst]$ ./procstuff My process ID: 4143 My parent process ID: 3696 My owner's user id: 1000 My owner's group id: 1000

Each of these data are supplied by library calls (that ultimately perform system calls). In order, getpid, getppid, getuid, and getgid. They are documented by running the man command on a Unix system (Sandbox works fine). Googling them works pretty well, too. You may compile your program as plain C or C++, as you like.

You are welcome to install Linux or BSD on your own equipment, or use the Sandbox server. If you need Sandbox credentials or a password change, drop by or email me.

When your program works correctly and looks nice, submit it here .
