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.
Header: Iprtrmib.h.
