Subject: [NUBY] Iteration in extensions

I can't get this simple thing to work. My extension uses two
functions, 'add_value' and 'add_values'. 'add_value' takes one value
and 'add_values' takes an array of values.

The idea is to have add_values to call add_value for each of the
values. Simple enough...

static VALUE add_value(VALUE self, VALUE val)
{
  # Code that works
}

static VALUE add_values(VALUE self, VALUE vals)
{
  rb_iterate(rb_each, vals, add_value, 0);
}

'add_value' works fine, but when I call 'add_values', I get this:
  TypeError: wrong argument type String (expected Data)


I guess I just don't understand how the rb_iterate is supposed to work...

Any pointers would be appreciated.
