send() returns 0 even though data is sent

Asked by AdrianBrown in Winsock, C Programming Language, TCP/IP

Tags: winsock, windows, c

Ive got a server/client winsock application that is using TCPNODELAY, ive got a problem that the send function from the server is trying to send 27 bytes but the return value is 0, yet the client does recieve 27 bytes. Infact it seems send always returns 0 bytes. Is this because of the TCPNODELAY flag? If so how do you tell how many bytes were actually sent?
