How about this? Works for me....

/*
 * Function Xt will use to process pending input on the RPC 
 * file descriptor;
 */

rpcListen(client_data, source, id)
caddr_t client_data;
int *source;
XtInputId *id;
{
    svc_getreq(1 << *source);
}

/*
 * main program
 */

main()
{
    int fd;

    svc_register(transp, ...);
    fd = transp->xp_sock;
    XtAppAddInput(_XtDefaultAppContext(), fd, XtInputReadMask,
                  rpcListen, 0);
    XtMainLoop();
}
