NET_DMA_PNP_NOTIFICATION structure (netdma.h)

  • Article
Note  The NetDMA interface is not supported in Windows 8 and later.
 
The NET_DMA_PNP_NOTIFICATION structure specifies a power management notification in the NetDMA interface.

Syntax

typedef struct _NET_DMA_PNP_NOTIFICATION {
  ULONG                         StructureRevision;
  ULONG                         StructureSize;
  NET_DMA_PNP_NOTIFICATION_CODE NotificationCode;
  PVOID                         Buffer;
  ULONG                         BufferLength;
} NET_DMA_PNP_NOTIFICATION, *PNET_DMA_PNP_NOTIFICATION;

Members

StructureRevision

The revision for this structure. The NetDMA provider driver must set this member to NET_DMA_PNP_NOTIFICATION_REVISION_1.

StructureSize

The size, in bytes, of the notification structure. This size does not include the size of the notification specific data at Buffer, if any. A NetDMA provider driver must set this member to sizeof(NET_DMA_PNP_NOTIFICATION).

NotificationCode

A value that identifies the DMA provider event. This value must be one of the values from the NET_DMA_PNP_NOTIFICATION_CODE enumeration.

Buffer

A pointer to notification-specific data, if any. NetDMA provider drivers set this member to NULL for NetDmaNotificationProviderPowerDown and NetDmaNotificationProviderPowerUp notifications.

BufferLength

The length, in bytes, of the notification-specific data at the Buffer member. NetDMA provider drivers set this member to zero for NetDmaNotificationProviderPowerDown and NetDmaNotificationProviderPowerUp notifications.

Remarks

To send a power management notification to the NetDMA interface, NetDMA provider drivers call the NetDmaPnPEventNotify function and provide a pointer to a NET_DMA_PNP_NOTIFICATION structure at the PnPEvent parameter.

Requirements

Requirement Value
Minimum supported client Supported for NetDMA 2.0 and NetDMA 1.1 drivers in Windows Server 2008.
