  • Article

The FWPM_VSWITCH_EVENT0 structure contains information about a vSwitch event.

Syntax

typedef struct FWPM_VSWITCH_EVENT0_ {
  FWPM_VSWITCH_EVENT_TYPE eventType;
  wchar_t                 *vSwitchId;
  union {
    struct {
      ULONG  numvSwitchFilterExtensions;
      LPWSTR *vSwitchFilterExtensions;
    } positionInfo;
    struct {
      BOOL   inRequiredPosition;
      ULONG  numvSwitchFilterExtensions;
      LPWSTR *vSwitchFilterExtensions;
    } reorderInfo;
  };
} FWPM_VSWITCH_EVENT0;

Members

eventType

Type: FWPM_VSWITCH_EVENT_TYPE

The type of vSwitch event.

vSwitchId

Type: wchar_t*

GUID that identifies a vSwitch.

positionInfo

Available when eventType is FWPM_VSWITCH_EVENT_FILTER_ADD_TO_FILTER_ENGINE_NOT_IN_REQUIRED_POSITION.

positionInfo.numvSwitchFilterExtensions

Type: ULONG

The number of vSwitch filter extensions.

positionInfo.vSwitchFilterExtensions

Type: LPWSTR*

size_is(numvSwitchFilterExtensions)

Array of strings identifying other vSwitch extensions.

reorderInfo

Available when eventType is FWPM_VSWITCH_EVENT_FILTER_ENGINE_REORDER.

reorderInfo.inRequiredPosition

Type: BOOL

True if the filter engine is in the required position to correctly enforce committed filters; otherwise, false.

reorderInfo.numvSwitchFilterExtensions

Type: ULONG

The number of vSwitch filter extensions.

reorderInfo.vSwitchFilterExtensions

Type: LPWSTR*

size_is(numvSwitchFilterExtensions)

Array of strings identifying other vSwitch extensions.

Remarks

For the unnamed union, switch_is(eventType), switch_type(FWPM_VSWITCH_EVENT_TYPE).
