This RFE requests optional parameters in a function synopsis. Traditional UNIX
man pages address this problem by repeating the signature:

int foo(int bar);
int foo(int bar, char *baz);
etc.

But overloaded functions have become fairly common so it seems likely
that others have been faced with this issue.

How did you deal with it? What markup would you like to see?

                                        Be seeing you,
                                          norm
