[LIP] ONC RPC

Hi all,

When trying to run the first example of chapter on RPC from UNPv2 by Stevens, 
I am constantly getting a segfault (after checkpoint 2, in the client code 
appended below). Can anyone please hint on why is this happening? I am using 
RHL9 on a P-III box.

The .x fle is as follows:

/* input (argument) */
struct square_in {
	long arg1;
};

/* output (result) */
struct square_out {
	long res1;
};

program SQUARE_PROG {
	version SQUARE_VERS {
		/* procedure number 1 */
		square_out SQUAREPROC(square_in) = 1;
	} = 1;
} = 0x31230000;


The RPC client is as follows:

#include <stdio.h>
#include <rpc/rpc.h>
#include "square.h"

void err_quit(char *format, char *addons) {
	printf(format, addons);
	exit(1);
}

/* display checkpoint */
void cp(int cpnum) {
	printf("\n-----Checkpoint %d-----", cpnum);
}

int main(int argc, char **argv) {
	CLIENT *c1;
	square_in  in;
	square_out *p_out;
	long val;
	
	if (argc != 3) {
		err_quit("%s", "Usage: client <hostname> <integer-value>");
	}
	cp(1);
	
	/* create RPC client object */
	c1 = clnt_create(argv[1], SQUARE_PROG, SQUARE_VERS, "tcp");
	cp(2);
	
	/* prepare input params */
	val = atol(argv[2]);
	printf("\nValue of argv[2] = %d", val);
	in.arg1 = 10L;
	cp(3);
	
	/* make the RPC call */
	p_out = squareproc_1(&in, c1);
	cp(4);
	
	/* dunno if it failed or passed */
	if (p_out == NULL) {
		err_quit("%s", clnt_sperror(c1, argv[1]));
	}
	else {
		printf("Result: %ld\n", p_out->res1);
	}
	return 0;
}
