NDK_FN_ARM_CQ callback function (ndkpi.h)

The NdkArmCq (NDK_FN_ARM_CQ) function arms an NDK completion queue (CQ) notification.

Syntax

NDK_FN_ARM_CQ NdkFnArmCq;

void NdkFnArmCq(
  [in] NDK_CQ *pNdkCq,
  [in] ULONG Type
)
{...}

Parameters

[in] pNdkCq

A pointer to an NDK completion queue object (NDK_CQ).

[in] Type

The type of notification to arm. The following notification types are defined:

Term	Description
NDK_CQ_NOTIFY_ERRORS	Notify if there are any completion queue errors such as a completion queue overrun or catastrophic failure.
NDK_CQ_NOTIFY_ANY	Notify of the next successful completion in the completion queue.
NDK_CQ_NOTIFY_SOLICITED	Notify when the completion queue receives a send request that includes the ND_OP_FLAG_SEND_AND_SOLICIT_EVENT flag.

Return value

None

Remarks

After the NDK consumer arms a completion queue (CQ) notification, the provider calls the NdkCqNotificationCallback callback function (the NDK_FN_CQ_NOTIFICATION_CALLBACK routine that the consumer specified when the CQ was created with the NdkCreateCq (NDK_FN_CREATE_CQ) function) when the specified type of notification is due.

If the CQ is closed while a call to NdkCqNotificationCallback is in-progress, the close request will remain pending until NdkCqNotificationCallback returns control to the provider. After the close request is completed, the provider will not call NdkCqNotificationCallback.
