Name-to-Address Translation (ONC+ Developer's Guide)

Name-to-Address Translation

Each transport has an associated set of routines that translate between universal network addresses (string representations of transport addresses) and the local address representation. These universal addresses are passed around within the RPC system (for example, between rpcbind and a client). A run-time linkable library that contains the name-to-address translation routines is associated with each transport. Table 2-7 shows the main translation routines.

For more details on these routines, see the netdir(3NSL) man page and the Transport Interfaces Programming Guide. Note that the netconfig structure in each case provides the context for name-to-address translations.

Table 2-7 Name-to-Address Translation Routines


`netdir_getbyname()`	Translates from host/service pairs (e.g. `server1`, `rpcbind`) and a `netconfig` structure to a set of `netbuf` addresses. `netbufs` are Transport Level Interface (TLI) structures that contain transport-specific addresses at run-time.
	Translates from netbuf addresses and a `netconfig` structure to 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.
