NdisDprAllocatePacket (Compact 2013)

3/26/2014

NdisDprAllocatePacket allocates and initializes a packet descriptor. Because Windows Embedded Compact 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.

Return Value

The following table shows the return values for this function.

Value

Description

NDIS_STATUS_SUCCESS

NDIS_STATUS_RESOURCES
