It depends on what your needs are. If your not actually using the 
arguments then you can pass in 0 and null, or 1 and the name of the 
application.

As an alternative, most platforms have an API for getting the arguments 
passed to an application.

Mac OS X: extern (C) char*** _NSGetEnviron();
Posix: extern (C) extern char** environ;

Don't know about Windows.
