/*
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.
