As others have mentioned, if you really want recursion it's best to
have a separate recursive function that you call from main. It's
legal to call main recursively, but the new invocation will (probably)
have no way of knowing that it's not the original one, so it will try
to process the command-line arguments all over again. (You can pass
in extra information in the parameters, or you can use a static
variable, but both approaches are kludges.)
But since you said you need to "jump to the start of main", I suspect
what you really need is not recursion but simply a loop. Recursion is
a powerful tool, but you shouldn't use it unless it's appropriate.

We must do something. This is something. Therefore, we must do this.
