program to create output with a table of contents

[jt at druca.UUCP]

I attempted to compile the program (that generates a table of contents)
submitted to net.sources about a week ago only to find that dup2 is
unknown here.  What does dup2 do?  Is it available on USG UNIX(tm)?  

Any information would be appreciated.  Thanks in advace.
