\defgroup keys_iterator Iterating on keys names The keys iterator is designed to get the key names defined in a message. Key names on which the iteration is carried out can be filtered through their attributes or by the namespace they belong to. @param h : the handle whose keys you want to iterate @param filter_flags : flags to filter out some of the keys through their attributes @param name_space : if not null the iteration is carried out only on keys belonging to the namespace passed. (NULL for all the keys) @return keys iterator ready to iterate through keys according to filter_flags and namespace
