.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.
|
||
|
|
.Pp
|
||
|
|
.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 .
|
||
|
|
.Fa svcaddr
|
||
|
|
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.
|
||
|
|
.Pp
|
||
|
|
.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.
|
||
|
|
.Fn rpcb_gettime
|
||
|
|
can be used to synchronize the time between the
|
||
|
|
client and the remote server.
|
||
|
|
.Pp
|
||
|
|
.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 parameter
|
||
|
|
.Fa svcaddr
|
||
|
|
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 parameters).
|
||
|
|
.Pp
|
||
|
|
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.
|
||
|
|
.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.
|
||
|
|
.Pp
|
||
|
|
.It Fn rpcb_set
|
||
|
|
An interface to the rpcbind
|
||
|
|
service, which establishes a mapping between the triple
|
||
|
|
[
|
||
|
|
.Fa prognum ,
|
||
|
|
.Fa versnum ,
|
||
|
|
.Fa netconf-\*[Gt]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.
|
||
|
|
.Pp
|
||
|
|
.It Fn rpcb_unset
|
||
|
|
An interface to the rpcbind
|
||
|
|
service, which destroys the mapping between the triple
|
||
|
|
[
|
||
|
|
.Fa prognum ,
|
||
|
|
.Fa versnum ,
|
||
|
|
.Fa netconf-\*[Gt]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
|
||
|
|
[
|
||
|
|
.Fa prognum ,
|
||
|
|
.Fa versnum ,
|
||
|
|
.Fa 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.
