This structure contains statistics for the TCP protocol running on the local computer.

typedef struct _MIB_TCPSTATS {DWORD dwRtoAlgorithm;DWORD dwRtoMin; DWORD dwRtoMax; DWORD dwMaxConn; DWORD dwActiveOpens; DWORD dwPassiveOpens; DWORD dwAttemptFails; DWORD dwEstabResets; DWORD dwCurrEstab; DWORD dwInSegs; DWORD dwOutSegs; DWORD dwRetransSegs; DWORD dwInErrs; DWORD dwOutRsts; DWORD dwNumConns; } MIB_TCPSTATS,*PMIB_TCPSTATS;

Members

  • dwRtoAlgorithm**
    The retransmission time-out algorithm in use. The following table shows the possible values. This member can be one of these values.
    Value Description
    MIB_TCP_RTO_CONSTANT Constant Time-out
    MIB_TCP_RTO_RSRE MIL-STD-1778 Appendix B
    MIB_TCP_RTO_VANJ Van Jacobson's Algorithm
    MIB_TCP_RTO_OTHER Other
  • dwRtoMin**
    The minimum retransmission time-out value in milliseconds.
  • dwRtoMax**
    The maximum retransmission time-out value in milliseconds.
  • dwMaxConn**
    The maximum number of connections. If this member is -1, the maximum number of connections is dynamic.
  • dwActiveOpens**
    The number of active opens. In an active open, the client is initiating a connection with the server.
  • dwPassiveOpens**
    The number of passive opens. In a passive open, the server is listening for a connection request from a client.
  • dwAttemptFails**
    The number of failed connection attempts.
  • dwEstabResets**
    The number of established connections that have been reset.
  • dwCurrEstab**
    The number of currently established connections.
  • dwInSegs**
    The number of segments received or transmitted.
  • dwOutSegs**
    The number of segments transmitted. This number does not include retransmitted segments.
  • dwRetransSegs**
    The number of segments retransmitted.
  • dwInErrs**
    The number of errors received.
  • dwOutRsts**
    The number of segments transmitted with the reset flag set.
  • dwNumConns**
    The cumulative number of connections.

Requirements

OS Versions: Windows CE 3.0 and later.
