Write a program that lists the process ID and command name for all processes being run by the user named in the program's command-line argument. (You may find the userIdFromName() function from Listing 8-1, on page 159, useful.) This can be done by inspecting the Name: and Uid: lines of all of the /proc/PID/status files on the system. Walking through all of the /proc/PID directories on the system requires the use of readdir(3), which is described in Section 18.8. Make sure your program correctly handles the possibility that a /proc/PID directory disappears between the time that the program determines that the directory exists and the time that it tries to open the corresponding /proc/PID/status file.
