Subject: Help embedding Ruby in Visual C++ project

Hi,
I am trying to embed Ruby within a Visual C++ project, but I am having
trouble loading my script file.

How do I tell the Ruby interpreter where to look for my script file?

If I use ruby_options(), then my program hangs.  So, I am trying to
pass the "-S" flag to Ruby, and I have set RUBYPATH to the directory
where "test.rb" lives.

Note: I am able to load the script if I put the script in the same
directory as my source files (which isn't the same directory as the
built C++ .exe).  I do not understand why this works.  Ideally, I would
like to tell the Ruby interpreter where to find my "test.rb" script.
How do I do this?  Thanks in advance for your help.

Here is a code snippet:
int state;
int rargc=2;
char *rargv[2], rarg1[MAX_PATH]

strcpy(rarg1, "-S");
rargv[0] = "ruby";
rargv[1] = rarg1;

NtInitialize(&rargc, (char ***)&rargv);

ruby_init();
ruby_init_loadpath();

rb_load_protect(rb_str_new2("test.rb"), Qfalse, &state);
