HSE_REQ_IS_CONNECTED

  • [アーティクル]

This support function can be used to determine if the client is still connected. This call is expensive for out-of-process applications since an RPC call must occur between the DLLHOST.exe and Inetinfo.exe processes.

BOOL ServerSupportFunction(
      HCONN ConnID,
      DWORD dwServerSupportFunction,
      LPVOID lpvBuffer,
      LPDWORD NULL,
      LPDWORD NULL
);

Parameters

  • ConnID
    Specifies the connection identifier of the client to which the response data should be sent.

  • dwServerSupportFunction
    The name of the Server Support function, which in this case must be set to HSE_REQ_IS_CONNECTED.

  • lpvBuffer
    Points to a global persisted BOOL that will contain the status of the client connection.

  • NULL
    Set to NULL.

  • NULL
    Set to NULL.
