+ * Memory is allocated on the stack frame by g_alloca() and it will be automatically deallocated
+ * during exit of current function (or current block if variable sized variables present there).
+ * You cannot deallocate or reallocate such memory in any other way.
+ *
+ * @Returns: Duplicated @string. You may modify its items if the length is not changed.
