Subject: debugging ruby extensions

Hello!

Is there a handy function to display messages to stdout/sterr inside
a ruby extension.

I thougth that:

 if ((RARRAY(x) == NULL) || (RARRAY(y) == NULL))
    {
      rb_warn ("2nd and 3rd parameter must be arrays!\n");
      return Qnil;
    } 
					
Would do such a thing.

BTW, is this a nice way to determine if an argument to a method
is an array of objects?
