rpc_svc_reg: svc_freeargs, svc_getargs, svc_getreqset,
svc_getrpccaller, svc_run, svc_sendreply - library routines for RPC
servers
DESCRIPTION
These routines are part of the RPC library which allows C language
programs to make procedure calls on other machines across the network.
These routines are associated with the server side of the RPC mechanism.
Some of them are called by the server side dispatch function, while
others [such as svc_run] are called when the server is initiated.
Routines
#include <rpc/rpc.h>
int
svc_freeargs(SVCXPRT *xprt, xdrproc_t inproc, void *in);
A function macro that frees any data allocated by the RPC/XDR system
when it decoded the arguments to a service procedure using
svc_getargs. This routine returns 1 if the results were
successfully freed, and 0 otherwise.
int
svc_getargs(SVCXPRT *xprt, xdrproc_t inproc, void *in);
A function macro that decodes the arguments of an RPC request
associated with the RPC service transport handle xprt. The
parameter in is the address where the arguments will be placed;
inproc is the XDR routine used to decode the arguments. This
routine returns 1 if decoding succeeds, and 0 otherwise.
void
svc_getreqset(fd_set *rdfds);
This routine is only of interest if a service implementor does not
call svc_run, but instead implements custom asynchronous event
processing. It is called when poll has determined that an RPC
request has arrived on some RPC file descriptors; rdfds is the
resultant read file descriptor bit mask. The routine returns when
all file descriptors associated with the value of rdfds have been
serviced
struct netbuf *
svc_getrpccaller(SVCXPRT *xprt);
The approved way of getting the network address of the caller of a
procedure associated with the RPC service transport handle xprt.

void
svc_run(void);
This routine never returns. It waits for RPC requests to arrive,
and calls the appropriate service procedure using svc_getreqset when
one arrives. This procedure is usually waiting for a poll library
call to return.
int
svc_sendreply(SVCXPRT *xprt, xdrproc_t outproc,
void *out);
Called by an RPC service's dispatch routine to send the results of a
remote procedure call. The parameter xprt is the request's
associated transport handle; outproc is the XDR routine which is
used to encode the results; and out is the address of the results.
This routine returns 1 if it succeeds, 0 otherwise.
