Description

CTL_TCP_SOCKET_CONNECTION_STATE_t is a condensed version of the complete set of states defined by RFC793. Whilst this should be self-explanatory we document the states anyway:

CTL_TCP_SOCKET_STATE_CLOSED

Socket has never been open, is invalid, or has been closed.

CTL_TCP_SOCKET_STATE_CONNECTING

Socket is connecting.

CTL_TCP_SOCKET_STATE_CONNECTED

Socket has completed three-way handshake and is ready for business.

CTL_TCP_SOCKET_STATE_CLOSING

Socket is closing.
