NAME
rpc_svc_reg: svc_freeargs, svc_getargs, svc_getreqset,
svc_getrpccaller, svc_run, svc_sendreply - library rou-
tines 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 svcrun] are called
when the server is initiated.
Routines
#include <rpc/rpc.h>
int
svcfreeargs(const SVCXPRT *xprt, const xdrproct inproc, char *in);
A function macro that frees any data allocated by the
RPC/XDR system when it decoded the arguments to a ser-
vice procedure using svcgetargs. This routine returns
1 if the results were successfully freed, and 0 other-
wise.
int
svcgetargs(const SVCXPRT *xprt, const xdrproct inproc, caddrt *in);
A function macro that decodes the arguments of an RPC
request associated with the RPC service transport han-
dle 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
svcgetreqset(fdset *rdfds);
This routine is only of interest if a service implemen-
tor does not call svcrun, but instead implements cus-
tom 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

RPCSVCREG(3N-SVR4)RISC/os Reference Manual RPCSVCREG(3N-SVR4)
The approved way of getting the network address of the
caller of a procedure associated with the RPC service
transport handle xprt.
void
svcrun(void);
This routine never returns. It waits for RPC requests
to arrive, and calls the appropriate service procedure
using svcgetreqset when one arrives. This procedure
is usually waiting for a poll library call to return.
int
svcsendreply(const SVCXPRT *xprt, const xdrproct outproc,
const caddrt *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.
