Description

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

Members

`Header`

The NDIS_OBJECT_HEADER structure for the NDIS_POLL_CHARACTERISTICS structure. Set the members of this structure as follows:

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.

`PollHandler`

An entry point for the NdisPoll callback function that NDIS invokes to poll the driver for receive indications and send completions.

Remarks

Miniport drivers initialize the NDIS_POLL_CHARACTERISTICS structure and then pass it to NDIS when calling NdisRegisterPoll.
