This function releases a buffer descriptor obtained in a preceding call to the NdisAllocateBufferfunction.
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 NdisFreePacketfunction 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 NdisUnchainBufferAt XXXfunctions 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.
