Name-to-address translation
Each transport has an associated set of routines that convert between
universal network addresses (string representations
of transport addresses) and their local address representation.
These universal addresses are passed around within the RPC system (for
example, between
rpcbind
and a client).
When any programming interface to the transport layer is made, a
transport-specific name-to-address translation routine is called to
convert the universal address into local form.
Each transport has
associated with it a run-time loadable library that contains the
name-to-address translation routines.
The main translation routines are:
netdir_getbyname:-
Translates from host/service pairs and a
netconfig
structure (for example, server1, rpcbind) to a set of
netbuf
addresses.
netbuf's
are
X/Open
Transport Interface (XTI)
structures that are used at run-time to contain transport-specific addresses.
netdir_getbyaddr:-
Translates from
netbuf
addresses and a
netconfig
structure into host/service pairs.
uaddr2taddr:-
Translates from universal addresses and a
netconfig
structure to
netbuf
addresses.
taddr2uaddr:-
Translates from
netbuf
addresses and a
netconfig
structure to universal addresses.
For more details on these routines, see the
netdir(3N)
manual page.
