Contains the Transmission Control Protocol (TCP) statistics that were collected for a socket.
A value from the TCPSTATE enumeration that indicates the state of the TCP connection.
The current maximum segment size (MSS) for the connection, in bytes.
The lifetime of the connection, in milliseconds.
TRUE if TCP time stamps are turned on for the connection; otherwise FALSE.
The current estimated round-trip time for the connection, in microseconds.
The minimum sampled round trip time, in microseconds.
The current number of sent bytes that are unacknowledged.
The size of the current congestion window, in bytes.
The size of the send window (SND.WND in RFC 793), in bytes.
The size of the receive window (RCV.WND in RFC 793), in bytes.
The size of the current receive buffer, in bytes. The size of the receive buffer changes dynamically when autotuning is turned on for the receive window.
The total number of bytes sent.
The total number of bytes received.
The total number of bytes reordered.
The total number of bytes retransmitted.
The number of calls of the Fast Retransmit algorithm.
The total number of duplicate acknowledgments received.
The total number of retransmission timeout episodes. Each episode can consist of multiple timeouts.
The total number of retransmitted synchronize control flags (SYNs).
To get an instance of this structure, call the WSAIoctl or LPWSPIoctl function with the SIO_TCP_INFO control code. Specify 0 for the lpvInBuffer field to retrieve the v0 version of this structure.
