hi sir,
I tried out something as you said.

I introduces this lines in my code,

getsockopt(s,SOL_SOCKET,SO_RCVBUF,&optval,&optlen);
printf("The value of optlen is %d\n",optlen);

It always displays 4.

I really have no idea about it. Do I need to use setsockopt options in my
receiver code ??
If so, what difference will it make ??
