[ruby-gnome2-devel-en] Converting array of Strings to C array of strings

[Nikolai W. <no...@bi...>]

This pattern is repeated a couple of times in glib2 and gtk2:

    for (i = 0; i < gargc; i++) {
        if (TYPE(RARRAY_PTR(argary)[i]) == T_STRING) {
            gargv[i+1] = RVAL2CSTR(RARRAY_PTR(argary)[i]);
        }
        else {
            gargv[i+1] = g_strdup("");
        }
    }

The TYPE() == T_STRING test seems like a poor choice.  Shouldn’t we at
least try using #to_str?

Also, as this pattern is repeated I really think that we should have a
utility function for it.  I’ll write it, but I need input on the
TYPE() comparison above.
