35 * The API defined by glibc allows a renderer to take multiple arguments
36 * This is obviously usable for things like (ptr+len) pairs etc.
37 * But the do not actually provide support for it at the end of the day,
38 * they offer only one argument to the arginfo function, but do accept
39 * >1 returns, although the do not check the types of those arguments
40 * argument
41 * Be compatible for now.
