Fires immediately after stopping tracking a session by HNTcpManager object.

Syntax:

void __stdcall OnSessionClose(DWORD_PTR Param, HANDLE hTcpSession, BOOL *pbNeed);

Parameters:

Param

[in] OnSessionClose event handler parameter. May be set by the TcpMgrSetOnClose function call.

hTcpSession

[in] HNTcpSession object handle.

pbNeed

[in,out] Flag that prevents HNTcpSession object deleting. If it is set in TRUE while OnSessionClose event handler works, the HNTcpManager component will not delete HNTcpSession object, and then OnSessionDelete (see HNFN_TCPDELETE) event handler will not be executed.

To delete HNTcpSession object later, you should call TcpMgrDeleteSession function manually. The default value of this flag is FALSE. This parameter value is ignored while TcpMgrResetSessions, TcpMgrResetOnTimeOut, and TcpMgrDeleteSession functions executing.

Description:

Set this event handler to make necessary actions at the moment of stopping tracking a session by HNTcpManager object. This event handler is called in the context of a thread, which has called the following functions: TcpMgrProcessPacket, TcpMgrResetSessions, TcpMgrResetOnTimeOut, TcpMgrCloseSession, TcpMgrDeleteSession.

Use HNTcpSession.CloseReason [Get] property to get the reason of the session closing.
