+The list of interfaces consists of a series of name/interface pairs.
+The interface is returned via a simple function. This allows for
+platforms where the interface has to be "assembled" before it can
+be used, like DLDI on the NDS. For cases where a simple struct
+is available, wrapper functions are used.
+The list is terminated by a NULL/NULL entry.
