  • Article

The NDIS_POLL_CHARACTERISTICS structure contains a Poll object’s NdisPoll and NdisSetPollNotification callback pointers.

Syntax

typedef struct _NDIS_POLL_CHARACTERISTICS {
  NDIS_OBJECT_HEADER                 Header;
  NDIS_SET_POLL_NOTIFICATION_HANDLER SetPollNotificationHandler;
  NDIS_POLL_HANDLER                  PollHandler;
} NDIS_POLL_CHARACTERISTICS;

Members

  • Type = NDIS_OBJECT_TYPE_DEFAULT
  • Revision = NDIS_POLL_CHARACTERISTICS_REVISION_1
  • Size = NDIS_SIZEOF_NDIS_POLL_CHARACTERISTICS_REVISION_1

SetPollNotificationHandler

An entry point for the NdisSetPollNotification callback function that NDIS invokes when it wants the driver to enable or disable interrupts.
