编译运行

dong@ubuntu:~/nanomsg_demo$ gcc -o recv recv.c -lnanomsg
dong@ubuntu:~/nanomsg_demo$ ./recv
NODE0: RECEIVED 1 "hello,world !"
NODE0: RECEIVED 1 "hello,world !"
NODE0: RECEIVED 1 "hello,world !"

    return ;

  }

    printf("bind server sock failed\r\n");

    return ;

  }

  printf("server socket init success...\r\n");

  return ;

}

int main()

{

  int s_sock;

  char *tx_msg = "Hi, client !";

  char *rx_msg = NULL;

  if ( != server_sock_init(&s_sock)) {

    return;

  }

  while ()

  {

    int result = nn_recv(s_sock, &rx_msg, NN_MSG,NN_DONTWAIT);

    if (result > ) {

    printf("server Recieve: %s\r\n", rx_msg);

    nn_freemsg (rx_msg);

    }

    size_t len = strlen (tx_msg) + ;

    if (nn_send(s_sock, tx_msg, len, ) < ) {

    printf("server Send Msg Failed\r\n");

    nn_freemsg (tx_msg);

    }

    sleep();

  }

  return ;

}

while True:
