/* NAME
/* tok822_resolve 3
/* SUMMARY
/* address resolving, client interface
/* SYNOPSIS
/* #include <tok822.h>
/*
/* void tok822_resolve(addr, reply)
/* TOK822 *addr;
/* RESOLVE_REPLY *reply;
/*
/* void tok822_resolve_from(sender, addr, reply)
/* const char *sender;
/* TOK822 *addr;
/* RESOLVE_REPLY *reply;
/* DESCRIPTION
/* tok822_resolve() takes an address token tree and finds out the
/* transport to deliver via, the next-hop host on that transport,
/* and the recipient relative to that host.
/*
/* tok822_resolve_from() allows the caller to specify sender context
/* that will be used to look up sender-dependent relayhost information.
/* SEE ALSO
/* resolve_clnt(3) basic resolver client interface
