- * which size is the result of \a rows times \a cols.

+ * char* string (#xbt_string_t is just an helper type defined exactly to help the parsing macro to specify the semantic of the pointer),
+ * that \a father field is a simple reference, that the size of the array pointed by \a data is the \a length field, and that the

+ * that you want to be defined only in one C file.
+ * In that case, use the previous trick for common messages, and use
+ * #GRAS_DEFINE_TYPE_LOCAL for the private messages.
