FwxFirewallEventType

The FwxFirewallEventType enumerated type defines the types of events to which a filter may hook. Each value in this enumeration is a bit. Values can be combined by using the bitwise OR operator to specify a set of events.

enum FwxFirewallEventType {
  fwx_Connect_Tcp,
  fwx_Udp_Destination,
  fwx_Bind_Tcp,
  fwx_Bind_Udp,
  fwx_Listen,
  fwx_AcceptedConnection,
  fwx_GetHostByName,
  fwx_GetHostByAddr,
  fwx_ConnectionTerminating
  fwx_EstablishedConnection
};
