send() return value

[stratoforce]

Hello, i got a question, and would be nice if someone can help me.

1) Is it safe to closesocket() right after send() in case send returns the correct ammount of bytes sent?

I thought it was, but now im thinking maybe im wrong.
After having problems with a program im writing, i did some research and it seems that the return value of send (bytes sent if no error) is the ammount of bytes "sent" to some TCP buffer, wich will later send the bytes to the peer.

2) So, closing the socket right after send() can make it impossible to the peer to recv if the socket has been closed before the bytes were actually sent through the network?

Thanks in advance.

Yes, that can happen.
