Socket Error or nohup error ??

[jayasekar.k]

Hi friends,
1. I have created a client socket to receive a data from the server.
2. The data received from the server will be shown in the terminal.
3. i want to run this application as a background and i want to redirect the output to a file. and also i want to run this application even when i log out so i did as given below

nohup myprogram > foo.out 2> foo.err < /dev/null &

4. when i use
$tailf foo.out

Everything is fine. I can view the output

but
i cannot able to view the last data i received.

5. If i run that on terminal, everything is fine. i can able to see the data, even the last one i received.

If i run the same using nohup, i could not able to view the last received data.
Can any one help me out to solve this problem

Thanks in advance

The stdout stream is buffered, whereas stderr isn't. This is being exposed by nohup. What you need to do is flush stdout when you write to it in myprogram. If it is a C program, then use "fflush(stdout);". If C++ and you are using cout, then either make sure each output is terminated with the std::endl, std::ends, or std::flush manipulator. An embedded "\n" in C++ sent to std::cout will not flush the buffer, nor will a printf("\n") in C programs.

Thanks for you help. i tried with fflush and sync. But still no improvement.
one thing is that if i run the same on terminal without nohup, it is working fine
