yaaa I m using select call b4 doing read on socket .
so the code is somewhat like this

//thread 1

==========================================
int retval = select(.....)//Now the thread is blocked and it will be awaked whn something is thr to read from socket.


if(retval == -1)
cout<<"error"<<endl;
else
int numBytes = read(sockid,buf,SIZE);
============================================

is dis fine ????
