No, the parent/child child relationship can only be created via fork(2).
You can't re-parent an arbitary process.  Of course, init (process 1) is
a special case.  Processes whose parent exits before them have their
parent process id change to be that of init when the parent exits.

Yes, declare:

    int  gargc;
    char *gargv[];

as globals and in main() go:

    main(argc, argv)
    int  argc;
    char *argv[];
    {
	gargc = argc;
	gargv = argv;

	...
    }

Isn't this one a FAQ in comp.lang.c?
