FwxFirewallEventType Enumeration

  • Article

The FwxFirewallEventType enumerated type contains values that specify the types of events raised by the Microsoft Firewall service for which a filter may receive notifications. Each value in this enumeration represents a single bit. Values can be combined by using the bitwise OR operator to specify a set of events.

Syntax

typedef enum FwxFirewallEventType {
  fwx_Connect_Tcp             = 0x00000001,
  fwx_Udp_Destination         = 0x00000002,
  fwx_Bind_Tcp                = 0x00000004,
  fwx_Bind_Udp                = 0x00000008,
  fwx_Listen                  = 0x00000010,
  fwx_AcceptedConnection      = 0x00000020,
  fwx_GetHostByName           = 0x00000040,
  fwx_GetHostByAddr           = 0x00000080,
  fwx_ConnectionTerminating   = 0x00000100,
  fwx_EstablishedConnection   = 0x00000200
} FwxFirewallEventType;
