Question: Can UNIX fork return an error? Why or why not?

Note: You can answer this question by looking at the manual page for fork, but before you do that, think about what the fork system call does. If you were designing this call, would you need to allow fork to return an error? Note: A manual page (or "man page") is a standard way of documenting Unix system calls and utility programs. On a Unix machine, you can access a manual page by running the man command (e.g., man fork). Another way to find manual pages is via web search (e.g., search for man fork and many of the top results will be manual pages for the fork system call.)
