socket

I'm implementing an FTP like protocol in Linux (homework) and I came upon the following problem: the client may be able to connect() and write() before the other side managed to do accept() (but after it did listen()). How can I prevent the write operation from working without relying on passing messages like "accept succeeded, you can write now" in a different communication channel?
