SIGIO + TCP communication.

Hi,

I used SIGIO signal when ever soket gets some information and i am
fetching asynchronously. But some scenario sender blocked and receiver
also blocked because buffer is ful and no way emit SIGIO signal to
processor.

i do not know how to resolve this problem.. i thought reading complete
receiver buffer on while loop but it able to read only few packets.

is there any way to check the buffer has some data in this
scenario . ?? Please help me with your guidence.

Thanks in Advance
