NdisFreePacket

  • 發行項

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

VOID NdisFreePacket(
IN PNDIS_PACKET Packet );

Parameters

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

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.

A driver that calls this function runs at IRQL <= DISPATCH_LEVEL.

Requirements

Runs on Versions Defined in Include Link to
Windows CE OS 2.0 and later Ndis.h    

Note   This API is part of the complete Windows CE OS package as provided by Microsoft. The functionality of a particular platform is determined by the original equipment manufacturer (OEM) and some devices may not support this API.
