IFWXConnection::Deny method

Applies to: desktop apps only

The Deny method denies the current operation on the connection object.

Syntax

HRESULT Deny(
  [in]  DWORD Reserved
);

Parameters

• Reserved [in]
  Reserved for future use. The parameter value must be zero.

Return value

This method can return one of these values.

• S_OK
  The connection will be denied.

• E_INVALIDARG
  Invalid value was passed to the Reserved parameter.

• FWX_E_BAD_CONTEXT
  The method was not called while handling any of the supported events.

Remarks

This method is rarely used. Using policy rules administration methods is the preferred way to control user activity.

This method must only be called in the context of the IFWXSessionFilter::FirewallEventHandler method while handling events of types:

• fwx_AcceptedConnection
• fwx_Bind_Udp
• fwx_Bind_Tcp
• fwx_Connect_Tcp

The action that caused the event will be canceled. A bind operation will fail with error code 10048 (WSAEADDRINUSE). A connect operation will fail with error code 10061 (WSAECONNREFUSED). An accepted connection will be aborted.

Note  For an event of type fwx_Udp_Destination, use the IFWXUdpDestination::Deny method instead of the IFWXConnection::Deny method. Outbound UDP packets sent to a denied destination will be discarded.
