svc_getargs()

The svc_getargs() call uses the XDR routine inproc to decode the arguments of an RPC request associated with the RPC service transport handle xprt. The results are placed at address in.

Syntax

#include <rpc\rpc.h>

bool_t
svc_getargs(xprt, inproc, in)
SVCXPRT *xprt;
xdrproc_t inproc;
char *in;

Parameters

xprt

Pointer to the service transport handle.

XDR routine that decodes the arguments.

Pointer to the decoded arguments.

Return Values

The value 1 indicates success; the value 0 indicates an error.

Examples

#define RMTPROGNUM   (u_long)0x3fffffffL#define RMTPROGVER   (u_long)0x1L

...

SVCXPRT *transp;

transp = svcudp_create(RPC_ANYSOCK);
if (transp == NULL)
   {
    fprintf(stderr, "can't create an RPC server transport\n");
    exit(-1);
   }
pmap_unset(RMTPROGNUM, RMTPROGVER);
if (!svc_register(transp, RMTPROGNUM, RMTPROGVER, rmtprog, IPPROTO_UDP))
   {
    fprintf(stderr, "can't register rmtprog() service\n");
    exit(-1);
   }
printf("rmtprog() service registered.\n");

svc_run();
printf("Error:svc_run should never reach this point \n");
exit(1);

rmtprog(rqstp, transp)
struct svc_req *rqstp;
SVCXPRT *transp;
{
    int intrecv;

    switch((int)rqstp->rq_proc)
       {
           case PROCNUM1:
                    svc_getargs(transp, xdr_int, &intrecv);
                      ...
