Check the stringfields header file here:

    http://svnview.digium.com/svn/asterisk/branches/1.8/include/asterisk/stringfields.h?view=markup

The equivalent is:

    ast_string_field_set()

However, that would still blow up in your example code (though I know it's just an example).  The string fields require some initialization before you can use them, so you can't just declare a queue on the stack like that.
