 * @note If you need more than (*$m2c_node_param_ref_lname) bytes of memory,
 *       allocate it using malloc() and update $m2c_node_param_ref_name.
 *       <b>DO NOT</b> free the previous pointer.
 *       The MFD helper will release the memory you allocate.
 *
 * @remark If you call this function yourself, you are responsible
 *         for checking if the pointer changed, and freeing any
 *         previously allocated memory. (Not necessary if you pass
 *         in a pointer to static memory, obviously.)
