* \brief Helper macro to iterate over the children of a compound node.
* \param[in,out] pos Iterator variable for the current node.
* \param[in] node Handle to the compound configuration node to iterate over.
*
* Use this macro like a \c for statement, e.g.:
* \code
* snd_config_iterator_t pos;
* snd_config_for_each(pos, node) {
* snd_config_t *entry = snd_config_iterator_entry(pos);
* ...
* }

* This macro does not allow deleting or removing the current node.
