The function .Fn form_fields will return a pointer to array of attach fields for the given form, this array is not .Dv NULL terminated, fields may be attached to the given form by calling .Fn set_form_fields . The .Fa fields argument in this function is a pointer to a .Dv NULL terminated array of fields that will be attached to the form. If there are already fields attached to the form then they will be detached before the new fields are attached. The new fields given must not be attached to any other form. The .Fn move_field function will move the given field to the location specified by .Fa frow and .Fa fcol . .Sh RETURN VALUES Functions returning pointers will return .Dv NULL if an error is detected. The functions that return an int will return one of the following error values:
