argv undeclared ? error

[john1984]

Hi Guys

[Duthomhas]

You've got some of syntax errors.

#include <ping.h>

...

const char* message = argv[ 2 ];

But I'm not sure that is entirely the problem. What is this code and how is it called?
As far as I can see, the Tcl interpreter never sees the "argv" item.
