NdisFreePacket (Compact 2013)

This function releases a packet that was allocated from a packet pool with the NdisAllocatePacket function and returns it to the free list.

Syntax

VOID NdisFreePacket(
  PNDIS_PACKET Packet
);

Parameters

  • Packet
    [in] Pointer to the packet descriptor returned by the NdisAllocatePacket or the NdisDprAllocatePacket function.

Return Value

None.

Remarks

Before calling this function, the driver must either call the NdisFreeBuffer function as many times as necessary to release all buffer descriptors chained to the packet, or call an NdisUnchainBufferAtXXX function as many times as necessary to save all pointers to buffer descriptors. Otherwise, memory associated with buffer descriptors in the chain remains unusable by the driver and by NDIS until the system is rebooted.

The driver must release any spin lock that it is holding before calling this function.
