NetTxQueueCreate function

Description

Creates a net transmit queue object.

Parameters

NetTxQueueInit [_Inout_]

A pointer to the NETTXQUEUE_INIT structure that the client driver received in EVT_NET_ADAPTER_CREATE_TXQUEUE.

TxQueueAttributes [_In_opt_]

A pointer to an initialized, caller-allocated 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.

Configuration [_In_]

A pointer to a caller-allocated NET_PACKET_QUEUE_CONFIG structure.

PacketQueue [_Out_]

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

Return value

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

Remarks

The client calls NetTxQueueCreate from within its EVT_NET_ADAPTER_CREATE_TXQUEUE 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.
