NdisFreeBuffer

  • 發行項

This function releases a buffer descriptor obtained in a preceding call to the NdisAllocateBuffer function.

VOID NdisFreeBuffer(
IN PNDIS_BUFFER Buffer );

Parameters

  • Buffer
    Pointer to a buffer descriptor.

Remarks

This function returns the given buffer descriptor to the free list.

A driver must not call the NdisFreePacket function with a packet to which buffers are chained because doing this causes a memory leak. Before it releases such a packet, the driver should either call this function as many times as necessary to release all buffer descriptors chained to the packet or call one of the NdisUnchainBufferAtXXX functions as many times as necessary to save the pointers to all chained buffer descriptors.

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.
