X.SH DESCRIPTION
X.IX "compilers" rpcgen "" "\fLrpcgen\fR \(em generate RPC protocols, C header files"
X.IX rpcgen "" "\fLrpcgen\fR \(em generate RPC protocol, C header files, and server skeleton"
X.IX RPC "generate protocols \(em \fLrpcgen\fR"
\fIrpcgen\fP is a tool that generates
X.B C
code to implement an
X.SM RPC
protocol. The input to \fIrpcgen\fP is a language similar
X.B C
known as RPC Language (Remote Procedure Call Language). Information
about the syntax of RPC Language is available in the \fI`rpcgen'
Programming Guide\fP.
X.LP
X.I rpcgen
is normally used as in the first synopsis where it takes an input file
and generates four output files. If the \fIinfile\fP is named \fIproto.x\fP,
then \fIrpcgen\fP will generate a header file in \fIproto.h\fP, XDR
routines in \fIproto_xdr.c\fP, server-side stubs in \fIproto_svc.c\fP
and client-side stubs if \fIproto_clnt.c\fP.
X.LP
The other synopses shown above are used when one does not want to
generate all the output files, but only a particular one. Their
usage is described in the \fBUSAGE\fP section below.
X.LP
The C-preprocessor, \fIcpp(1)\fP, is run on all input files before they are
actually
interpreted by \fIrpcgen\fP, so all the cpp directives are legal within
an \fIrpcgen\fP input file. For each type of output file, \fIrpcgen\fP defines
a special cpp symbol for use by the \fIrpcgen\fP programmer:
X.PP
X.PD 0
X.TP
X.SM RPC_HDR
defined when compiling into header files
X.TP
X.SM RPC_XDR
defined when compiling into XDR routines
X.TP
X.SM RPC_SVC
defined when compiling into server-side stubs
X.TP
X.SM RPC_CLNT
defined when compiling into client-side stubs
X.PD
X.PP
In addition, \fIrpcgen\fP does a little preprocessing of its own. Any line
beginning with `%' is passed directly into the output file, uninterpreted
by \fIrpcgen\fP.
X.LP
You can customize some of your XDR routines by leaving those data
types undefined. For every data type that is undefined, \fIrpcgen\fP
will assume that there exists a routine with the name `xdr_' prepended
to the name of the undefined type.
X.SH OPTIONS
X.IP \fB-c\fP
Compile into XDR routines.
X.IP \fB-h\fP
Compile into
X.B C
data-definitions (a header file)
X.IP "\fB-l\fP
Compile into a client-side stubs.
X.IP "\fB-s\fP \fItransport\fP"
Compile into server-side stubs, using the the given transport. The
supported transports
are \fBudp\fP and \fBtcp\fP. This option may be invoked more than once
so as to compile a server that serves multiple transports.
X.IP "\fB-m\fP
Compile into a server-side stubs, but do not produce a \fImain()\fP routine.
This option is useful if you want to supply your own \fImain()\fP.
X.IP "\fB-o\fP \fIoutfile\fP"
Specify the name of the output file. If none is specified, standard
output is used (\fB-c\fP, \fB-h\fP, \fB-l\fP and \fB-s\fP modes only).
X.SH "SEE ALSO"
\fI`rpcgen' Programming Guide\fP
X.SH BUGS
Nesting is not supported. As a work-around, structures can be declared at
top-level, and their name used inside other structures in order to achieve
the same effect.
X.LP
Name clashes can occur when using program definitions, since the apparent
scoping does not really apply. Most of these can be avoided by giving
unique names for programs, versions, procedures and types.

X.I prognum
is registered but not with version
X.IR versnum ,
it will still return a port number (for some version of the program)
indicating that the program is indeed registered.

X.IX rpc "" "RPC routines"
X.IX "remote procedure calls"
X.IX rpc "" "RPC routines"
X.IX "remote procedure calls"
X.SH SYNOPSIS AND DESCRIPTION
These routines allow C programs to make procedure
calls on other machines across the network.
First, the client calls a procedure to send a
data packet to the server.
Upon receipt of the packet, the server calls a dispatch routine
to perform the requested service, and then sends back a
reply.
Finally, the procedure call returns to the client.

X.B procnum
on the machine,
X.BR host .
The parameter
X.B in
is the address of the procedure's argument(s), and
X.B out
is the address of where to place the result(s);
X.B inproc
is used to encode the procedure's parameters, and
X.B outproc
is used to decode the procedure's results.
This routine returns zero if it succeeds, or the value of
X.B "enum clnt_stat"
cast to an integer if it fails.
The routine
X.B clnt_perrno
is handy for translating failure statuses into messages.
X.IP
Warning: calling remote procedures with this routine
uses

This routine creates a toy

client for the remote program
X.BR prognum ,
version
X.BR versnum .
The transport used to pass messages to the service is
actually a buffer within the process's address space, so the
corresponding
X.SM RPC
server should live in the same address space; see
X.BR svcraw_create .
This allows simulation of
X.SM RPC
and acquisition of

X.SH NAME
xdr \- library routines for external data representation
X.SH SYNOPSIS AND DESCRIPTION
These routines allow C programmers to describe
arbitrary data structures in a machine-independent fashion.
Data for remote procedure calls are transmitted using these
routines.

X.fi
X.ft R
X.IP
A filter primitive that translates between variable-length
arrays
and their corresponding external representations. The
parameter
X.B arrp
is the address of the pointer to the array, while
X.B sizep
is the address of the element count of the array;
this element count cannot exceed
X.BR maxsize .
The parameter
X.B elsize
is the
X.B sizeof
each of the array's elements, and
X.B elproc
is an
X.SM XDR
filter that translates between
the array elements' C form, and their external
representation.
This routine returns one if it succeeds, zero otherwise.

stream,
X.BR xdrs .
The routine returns an unsigned integer,
which indicates the position of the
X.SM XDR
byte stream.
A desirable feature of

X.IP
This routine initializes the
X.SM XDR
stream object pointed to by
X.BR xdrs .
The stream's data is written to a buffer of size
X.BR sendsize ;
a value of zero indicates the system should use a suitable
default. The stream's data is read from a buffer of size
X.BR recvsize ;
it too can be set to a suitable default by passing a zero
value.
When a stream's output buffer is full,
X.B writeit
is called. Similarly, when a stream's input buffer is empty,
X.B readit
is called. The behavior of these two routines is similar to
the
X.SM UNIX
system calls
X.B read
and
X.BR write ,
except that
X.B handle
is passed to the former routines as the first parameter.
Note that the
X.SM XDR
stream's
X.B op
field must be set by the caller.

and its corresponding external representation. It first
translates the discriminant of the union located at
X.BR dscmp .
This discriminant is always an
X.BR enum_t .
Next the union located at

is translated. The parameter
X.B choices
is a pointer to an array of
X.B xdr_discrim
structures. Each structure contains an ordered pair of
X.BR "[value, proc]" .
If the union's discriminant is equal to the associated
X.BR value ,
then the
X.B proc
is called to translate the union. The end of the
X.B xdr_discrim
structure array is denoted by a routine of value
X.SM NULL .
If the discriminant is not found in the

X.SM RPC
calls.
X.LP
When an
X.SM RPC
server is started, it will tell
X.B portmap
what port number it is listening to, and what
X.SM RPC
program numbers it is prepared to serve.
When a client wishes to make an
X.SM RPC
call to a given program number,
it will first contact
X.B portmap
on the server machine to determine
the port number where
X.SM RPC
packets should be sent.
X.LP
Normally, standard
X.SM RPC
servers are started by
X.BR inetd (8C),
so
X.B portmap
must be started before
X.B inetd
is invoked.
X.SH "SEE ALSO"
X.BR servers (5),
X.BR rpcinfo (8),
X.BR inetd (8)
X.SH BUGS
If
X.B portmap
crashes, all servers must be restarted.

X.SH DESCRIPTION
X.IX "rpcinfo command" "" "\fLrpcinfo\fP \(em report RPC information"
X.IX RPC "report RPC information \(em \fLrpcinfo\fR"
X.B rpcinfo
makes an
X.SM RPC
call to an
X.SM RPC
server and reports what it finds.
X.SH OPTIONS
X.TP
X.B \-p
Probe the portmapper on
X.IR host ,
and print a list of all registered
X.SM RPC
programs. If
X.I host
is not specified, it defaults to the value returned by
X.BR hostname (1).
X.TP
X.B \-u
Make an
X.SM RPC
call to procedure 0 of
X.I program
on the specified
X.I host
using
X.SM UDP\s0,
and report whether a response was received.
X.TP
X.B \-t
Make an
X.SM RPC
call to procedure 0 of
X.I program
on the specified
X.I host
using
X.SM TCP\s0,
and report whether a response was received.
X.TP
X.B \-b
Make an
X.SM RPC
broadcast to procedure 0 of the specified
X.I program
and
X.I version
using
X.SM UDP
and report all hosts that respond.
X.LP
The
X.I program
argument can be either a name or a number.
X.LP
If a
X.I version
is specified,
X.B rpcinfo
attempts to call that version of the specified
X.IR program .
Otherwise,
X.B rpcinfo
attempts to find all the registered version
numbers for the specified
X.I program
by calling version 0 (which is presumed not
to exist; if it does exist,
X.B rpcinfo
attempts to obtain this information by calling
an extremely high version
number instead) and attempts to call each registered version.
Note: the version number is required for the
X.B \-b
option.
X.SH EXAMPLES
To show all of the
X.SM RPC
services registered on the local machine use:
X.IP
X.B example% rpcinfo -p
X.LP
To show all of the
X.SM RPC
services registered on the machine named
X.B klaxon
use:
X.IP
X.B example% rpcinfo -p klaxon
X.LP
To show all machines on the local net that are running the Yellow Pages
service use:
X.IP
X.B "example% rpcinfo -b ypserv 'version' | uniq"
X.LP
where 'version' is the current Yellow Pages version obtained from the
results of the
X.B \-p
switch above.

X.SH BUGS
In releases prior to Sun\s-1OS\s0
3.0, the Network File System (\s-1NFS\s0) did not
register itself with the
portmapper;
X.B rpcinfo
cannot be used to make
X.SM RPC
calls to the
X.SM NFS
server on hosts running such releases.

X.LP
X.B rstat_svc
is a server which returns performance statistics
obtained from the kernel.
These statistics are graphically displayed by the Sun Microsystems program,
X.BR perfmeter (1).
The
X.B rstat_svc
daemon is normally invoked at boot time through /etc/rc.local.
X.PP
X.B rstat_svc
uses an RPC protocol defined in /usr/include/rpcsvc/rstat.x.
