Members
| Members | Description |
|---|---|
| TCPIP_TCP_STATE_LISTEN | Socket is listening for connections. |
| TCPIP_TCP_STATE_SYN_SENT | A SYN has been sent, awaiting an SYN+ACK. |
| TCPIP_TCP_STATE_SYN_RECEIVED | A SYN has been received, awaiting an ACK. |
| TCPIP_TCP_STATE_ESTABLISHED | Socket is connected and connection is established. |
| TCPIP_TCP_STATE_FIN_WAIT_1 | FIN WAIT state 1. |
| TCPIP_TCP_STATE_FIN_WAIT_2 | FIN WAIT state 2. |
| TCPIP_TCP_STATE_CLOSING | Socket is closing. |
| TCPIP_TCP_STATE_TIME_WAIT | 2MSL state. |
| TCPIP_TCP_STATE_CLOSE_WAIT | Waiting to close the socket. |
| TCPIP_TCP_STATE_LAST_ACK | The final ACK has been sent. |
| TCPIP_TCP_STATE_CLIENT_WAIT_DISCONNECT | Client socket lost connection, waiting for app close/disconnect. |
| TCPIP_TCP_STATE_CLIENT_WAIT_CONNECT | Client socket waiting for connection. |
| TCPIP_TCP_STATE_KILLED | Socket is killed; debug reporting state. |
