Passing character pointers from client to server in RPCGen

I am trying to send character pointers from rpc client to server in rpcgen for which below are the server and client programs

RPC program for RPC gen

struct clientinput {
    char * optype;
    char * word;
};

program DICTIONARY_PROG {
    version DICTIONARY_VERS {
        int USEDICTIONARY(clientinput) = 1;
    } = 1;
} = 0x23451113;

RPC Server

    #include "dictionary.h"

    int *
    usedictionary_1_svc(clientinput *argp, struct svc_req *rqstp)
    {
        static int  result;
        char *optype = (char*)malloc (10);
        char *word = (char*)malloc (10);

        char *a = argp->optype;
        char *b = argp->word;

        printf("Optype is %s\n", a);
        printf("Word is %s\n", b);

        printf("The optype is %s\n", strcpy(optype, argp->optype));
        printf("The word is %s\n", strcpy(word, argp->word));
        /*
         * insert server code here
         */

        return &result;
    }

RPC Client

#include "dictionary.h"


void
dictionary_prog_1(char *host, char *optype, char *word)
{
    CLIENT *clnt;
    int  *result_1;
    clientinput  usedictionary_1_arg;

    //strcpy(usedictionary_1_arg.optype, optype);
    //strcpy(usedictionary_1_arg.word, word);

    usedictionary_1_arg.optype = optype;
    usedictionary_1_arg.word = word;

    printf("Optype input is %s\n",usedictionary_1_arg.optype);
    printf("Word input is %s \n",usedictionary_1_arg.word);

#ifndef DEBUG
    clnt = clnt_create (host, DICTIONARY_PROG, DICTIONARY_VERS, "udp");
    if (clnt == NULL) {
        clnt_pcreateerror (host);
        exit (1);
    }
#endif  /* DEBUG */

    result_1 = usedictionary_1(&usedictionary_1_arg, clnt);
    if (result_1 == (int *) NULL) {
        clnt_perror (clnt, "call failed");
    }
#ifndef DEBUG
    clnt_destroy (clnt);
#endif   /* DEBUG */
}


int
main (int argc, char *argv[])
{
    char *host, *optype, *word;

    if (argc < 2) {
        printf ("usage: %s server_host\n", argv[0]);
        exit (1);
    }
    host = argv[1];
    optype = argv[2];
    word = argv[3];

    dictionary_prog_1 (host,optype,word);
exit (0);
}

Here is the output on the server side

Optyep is a
Word is e
The optype is a
The word is e

The problem i encounter here is that only first character of the character pointers which I have passed from server to client gets printed. I have tried possible combinations of using character pointers and could not find the reason. So can someone please help me figure out the reason for this?
