RPC program problem!

Hi,

I’m working on RPC in linux , I use Rpcgen to generate the files .
My program is to send an array to a server , the server returns 3 * array…

     // .x file
 
const maxnum=50;
struct inout_array
{
  int array;
 };
program MATMULT_PROG
{
  version MATMUL_VER{
  inout_array matmul(inout_array)=1;
 }=1;
}=0x23451689;
-----------------
//server.c 
 
#include "matmul.h"
inout_array *
matmul_1_svc(inout_array *argp, struct svc_req *rqstp)
{
static inout_array result;
inout_array x;
int i;
for (i=0;iarray.array_len;i++)
result.array.array_val[i]=argp->array.array_val[i]*3;
return &result;
}
--------------------------
//client.c
#include "matmul.h"
int main (int argc, char *argv[])
{ char *host;
host = argv[1];
CLIENT *clnt;
inout_array *result_1;
inout_array matmul_1_arg;
int i;
int a[maxnum]; //passed array to server
int tindex=4;
for(i=0;i<argc-2;i++)
a[i]=atoi(argv[tindex++]);
matmul_1_arg.array.array_val=a;
clnt = clnt_create (host, MATMULT_PROG, MATMUL_VER, "tcp");
if (clnt == NULL) {
clnt_pcreateerror (host);
exit (1);
}
result_1 = matmul_1(&matmul_1_arg, clnt);
if (result_1 == (inout_array * ) NULL) {
clnt_perror (clnt, "call failed");
}
 clnt_destroy (clnt);
for(i=0;iarray.array_len;i++)
printf("%d\n",result_1->array.array_val[i]);
exit (0);
}

   

I don't know what goes wrong here!

Thanks a lot!
