Your sysop recently quit due to what the law division calls "internal struggles". Less fancily, he hated you, and he hated his job. As a parting gift, he left you a program entitled SwanSong.c. Being curious and slightly daft, you of course decide to execute it. Your console immediately floods with errors to standard error output:
stderr ------ Line 4: Cannot exec a shared library directly. Line 5: Link has been severed. Line 5: Attempting to link in too many shared libraries. Line 7: Srmount error. Line 8: Too many users. Line 9: Name not unique on network. Line 14: RFS specific error. Line 18: Remote address changed. Line 18: Interrupted system call should be restarted. Line 18: Socket operation on non-socket.
What does your sysop's swan song mean?
Footnote: Bonus points if you can write a program that returns this output. I'm pretty sure it's not possible, and it's definitely not a requirement to solve the problem.
