NdisDprAllocatePacket (Windows CE 5.0)
NdisDprAllocatePacket allocates and initializes a packet descriptor. Because Windows CE does not support DPC IRQL, all NdisDprXXX functions perform identically to the non-DPR equivalent.
VOID NdisDprAllocatePacket(PNDIS_STATUSStatus,PNDIS_PACKET* Packet,NDIS_HANDLEPoolHandle);
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 Values
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. |
