+.Sh DESCRIPTION +These routines allow client C programs to make procedure +calls to the RPC binder service. +(see +.Xr rpcbind 8 ) +maintains a list of mappings between programs +and their universal addresses. +.Sh Routines +.Bl -tag -width XXXXX +.It 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 +.Dv NULL , +if the remote rpcbind could not be contacted. +.It 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 +.Dv TRUE +if it succeeds. +A return value of +.Dv 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 +.Va rpc_createerr +(see +.Xr rpc_clnt_create 3 ) +contains the +RPC status. +.It Fn rpcb_gettime +This routine returns the time on +.Fa host +in +.Fa timep . +If +.Fa host +is +.Dv NULL , +.Fn rpcb_gettime +returns the time on its own machine. +This routine returns +.Dv TRUE +if it succeeds, +.Dv FALSE +if it fails. +The +.Fn rpcb_gettime +function +can be used to synchronize the time between the +client and the remote server. +.It 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 +.Fn 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 +.Fn rpc_call +and +.Fn clnt_call +in +.Xr rpc_clnt_calls 3 +for the definitions of other arguments). +.Pp +This procedure should normally be used for a +.Dq ping +and nothing else. +This routine allows programs to do lookup and call, all in one step. +.Pp +Note: Even if the server is not running +.Fn rpcb_rmtcall +does not return any error messages to the caller. +In such a case, the caller times out. +.Pp +Note: +.Fn rpcb_rmtcall +is only available for connectionless transports. +.It 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 +.Dv TRUE +if it succeeds, +.Dv FALSE +otherwise. +(See also +.Fn svc_reg +in +.Xr rpc_svc_calls 3 . ) +If there already exists such an entry with rpcbind, +.Fn rpcb_set +will fail. +.It 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 +.Dv NULL , +.Fn 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 +.Dv TRUE +if it succeeds, +.Dv FALSE +otherwise. +Only the owner of the service or the super-user can destroy the mapping. +(See also +.Fn svc_unreg +in +.Xr rpc_svc_calls 3 . ) +.El +.Sh AVAILABILITY +These functions are part of libtirpc. +.Sh ENVIRONMENT +If RPCB_V2FIRST is defined, rpcbind protocol version tryout algorithm changes from v4,v2,v3 to v2,v4,v3. +.Sh SEE ALSO +.Xr rpc_clnt_calls 3 , +.Xr
