Creates a net receive queue object.

Syntax

NTSTATUS NetRxQueueCreate(
  [_Inout_]  NETRXQUEUE_INIT         *NetRxQueueInit,
  [_In_opt_] WDF_OBJECT_ATTRIBUTES   *RxQueueAttributes,
  [_In_]     NET_PACKET_QUEUE_CONFIG *Configuration,
  [_Out_]    NETPACKETQUEUE          *PacketQueue
);

Parameters

[_Inout_] NetRxQueueInit

A pointer to the NETRXQUEUE_INIT structure that the client driver received in its EVT_NET_ADAPTER_CREATE_RXQUEUE callback function.

[_In_opt_] RxQueueAttributes

A pointer to caller-allocated and initialized WDF_OBJECT_ATTRIBUTES structure. This parameter is optional and can be WDF_NO_OBJECT_ATTRIBUTES. However, if the client driver supplies this parameter, the ParentObject field must be NULL.

[_In_] Configuration

A pointer to a caller-allocated NET_PACKET_QUEUE_CONFIG structure.

[_Out_] PacketQueue

A pointer to a location that receives a handle to the new net receive queue object.

Return value

This function returns STATUS_SUCCESS if the operation succeeds. Otherwise, this function may return an appropriate NTSTATUS error code.

Remarks

The client calls NetRxQueueCreate from within its EVT_NET_ADAPTER_CREATE_RXQUEUE event callback function. For info on assigning context space to the new object, see Framework Object Context Space.

The NETPACKETQUEUE object is a standard WDF object. The framework manages its deletion, which occurs when the parent NETADAPTER object is deleted.
