NdisDprAllocatePacket (Windows Embedded CE 6.0)
1/6/2010
NdisDprAllocatePacket allocates and initializes a packet descriptor. Because Windows Embedded CE does not support DPC IRQL, all NdisDprXXX functions perform identically to the non-DPR equivalent.
Syntax
VOID NdisDprAllocatePacket(
PNDIS_STATUS Status,
PNDIS_PACKET* Packet,
NDIS_HANDLE PoolHandle
);
Parameters
- Status
[out] Pointer to a caller-supplied variable in which this function returns the final status of the request.
- Packet
[out] Pointer to a caller-supplied variable in which this function returns a pointer to the allocated packet descriptor.
- PoolHandle
[in] Specifies the handle returned by a preceding call to NdisAllocatePacketPool.
Return Value
The following table shows the return values for this function
| Value | Description |
|---|---|
NDIS_STATUS_SUCCESS |
The caller can use the packet descriptor returned at Packet. |
NDIS_STATUS_RESOURCES |
The free list for the packet pool currently has no available entries. A subsequent call to NdisDprFreePacket or NdisFreePacket will return the given entry to the free list. The variable at Packet is set to NULL. |
Requirements
| Header | ndis.h |
| Library | ndis.lib |
| Windows Embedded CE | Windows CE .NET 4.0 and later |
