read() is blocking until it receives at least one byte. To interrupt
it, wait until a time then issue an alarm() from another thread. The
following should solve your issue:
int readBytes=read(sd, &foo, 255);
if (readBytes == 0) { // client closed connection
close(sd);
}
if (readBytes < 0) // check errno for what's wrong, most likely,
connection will need to be
// closed.
