This code would be created in +.Pa proto_server.c . +.Pp +The server created can be started both by the port monitors +(for example, +.Em inetd +or +.Em listen ) +or by itself. +When it is started by a port monitor, +it creates servers only for the transport for which +the file descriptor 0 was passed. +The name of the transport must be specified +by setting up the environmental variable +.Ev PM_TRANSPORT . +When the server generated by +.Nm rpcgen +is executed, +it creates server handles for all the transports +specified in +.Ev NETPATH +environment variable, +or if it is unset, +it creates server handles for all the visible transports from +.Pa /etc/netconfig +file. +Note: +the transports are chosen at run time and not at compile time. +When the server is self-started, +it backgrounds itself by default. +A special define symbol +.Dv RPC_SVC_FG +can be used to run the server process in foreground. +.P +The second synopsis provides special features which allow +for the creation of more sophisticated +.Tn RPC +servers. +These features include support for user provided +.Li #defines +and +.Tn RPC +dispatch tables. +The entries in the +.Tn RPC +dispatch table contain: +.Pp +.Bl -inset -offset indent -compact +.It + +pointers to the service routine corresponding to that procedure, +.It + +a pointer to the input and output arguments, +.It + +the size of these routines +.El +.Pp +A server can use the dispatch table to check authorization +and then to execute the service routine; +a client library may use it to deal with the details of storage +management and +.Tn XDR +data conversion. +.Pp +The other three synopses shown above are used when +one does not want to generate all the output files, +but only a particular one. +Some examples of their usage is described in the +EXAMPLE +section below. +When +.Nm rpcgen +is executed with the +.Fl s +option, +it creates servers for that particular class of transports. +When +executed with the +.Fl n +option, +it creates a server for the transport specified by +.Em netid . +If +.Ar infile +is not specified, +.Nm rpcgen +accepts the standard input. +.Pp +The C preprocessor, +.Xr cpp 1 +is run on the input file before it is actually interpreted by +.Nm rpcgen +For each type of output file, +.Nm rpcgen +defines a special preprocessor symbol for use by the +.Nm rpcgen +programmer: +.Pp +.PD 0 +.TP 12 +.Dv RPC_HDR +defined when compiling into header files +.TP +.Dv RPC_XDR +defined when compiling into +.Tn XDR +routines +.TP +.Dv RPC_SVC +defined when compiling into server-side stubs +.TP +.Dv RPC_CLNT +defined when compiling into client-side stubs +.TP +.Dv RPC_TBL +defined when compiling into +.Tn RPC +dispatch tables +.PD +.Pp +Any line beginning with +.Sq % +is passed directly into the output file, +uninterpreted by +.Nm rpcgen +.Pp +For every data type referred to in +.Ar infile +.Nm rpcgen +assumes that there exists a +routine with the string +.Dq xdr_ +prepended to the name of the data type. +If this routine does not exist in the +.Tn RPC/XDR +library, it must be provided. +Providing an undefined data type +allows customization of +.Tn XDR +routines. +.Sh OPTIONS +.Bl -tag -width indent +.It Fl a +Generate all the files including sample code for client and server side. +.It Fl b +This generates code for the +.Tn SunOS4.1 +style of rpc.
