DESCRIPTION

These routines allow client C programs to make procedure calls to the RPC binder service. (see rpcbind(8)) maintains a list of mappings between programs and their universal addresses.

Routines

Fn rpcb_getmaps

An interface to the rpcbind service, which returns a list of the current RPC program-to-address mappings on Fa host . It uses the transport specified through Fa netconf to contact the remote rpcbind service on Fa host . This routine will return NULL if the remote rpcbind could not be contacted.

Fn rpcb_getaddr

An interface to the rpcbind service, which finds the address of the service on Fa host that is registered with program number Fa prognum , version Fa versnum , and speaks the transport protocol associated with Fa netconf . The address found is returned in Fa svcaddr . The Fa svcaddr argument should be preallocated. This routine returns TRUE if it succeeds. A return value of FALSE means that the mapping does not exist or that the RPC system failed to contact the remote rpcbind service. In the latter case, the global variable rpc_createerr (see rpc_clnt_create3) contains the RPC status.

Fn rpcb_gettime

This routine returns the time on Fa host in Fa timep . If Fa host is NULL rpcb_gettime ();
returns the time on its own machine. This routine returns TRUE if it succeeds, FALSE if it fails. The rpcb_gettime ();
function can be used to synchronize the time between the client and the remote server.

Fn rpcb_rmtcall

An interface to the rpcbind service, which instructs rpcbind on Fa host to make an RPC call on your behalf to a procedure on that host. The netconfig ();
structure should correspond to a connectionless transport. The Fa svcaddr argument will be modified to the server's address if the procedure succeeds (see rpc_call ();
and clnt_call ();
in rpc_clnt_calls3 for the definitions of other arguments).

This procedure should normally be used for a ``ping'' and nothing else. This routine allows programs to do lookup and call, all in one step.

Note: Even if the server is not running rpcb_rmtcall ();
does not return any error messages to the caller. In such a case, the caller times out.

Note: rpcb_rmtcall ();
is only available for connectionless transports.

Fn rpcb_set

An interface to the rpcbind service, which establishes a mapping between the triple Bq Fa prognum , versnum , netconf->nc_netid and Fa svcaddr on the machine's rpcbind service. The value of Fa nc_netid must correspond to a network identifier that is defined by the netconfig database. This routine returns TRUE if it succeeds, FALSE otherwise. (See also svc_reg ();
in rpc_svc_calls3.) If there already exists such an entry with rpcbind, rpcb_set ();
will fail.

Fn rpcb_unset

An interface to the rpcbind service, which destroys the mapping between the triple Bq Fa prognum , versnum , netconf->nc_netid and the address on the machine's rpcbind service. If Fa netconf is NULL rpcb_unset ();
destroys all mapping between the triple Bq Fa prognum , versnum , No all-transports and the addresses on the machine's rpcbind service. This routine returns TRUE if it succeeds, FALSE otherwise. Only the owner of the service or the super-user can destroy the mapping. (See also svc_unreg ();
in rpc_svc_calls3.)
