                    if(errno == EAGAIN) printf("No data\n");
            }

            if(buf_r[0]=='Q') break;

            buf_r[nread]=0;
            printf("data is：%s\n", buf_r);
            Sleep(1);
    }

    I think this program is supposed to be executed in unix box not on windows. I strongly feel that you are using windows (Just saw the headers, haven't gone through the program yet)

    Update
    Yup, it should be executed in unix box. I'll let you try this code in linux and get back with the results
