IPFreeBuff function

Do not write a firewall-hook driver to process incoming and outgoing packets. For more information, see Firewall-Hook Drivers.

The IPFreeBuff function releases memory for a chain of buffers and their descriptors.

Syntax

VOID IPFreeBuff(
  _In_ IPRcvBuf *pRcvBuf
);

Parameters

• pRcvBuf [in]
  Pointer to an IPRcvBuf structure that represents the buffer descriptor at the head of a chain of buffer descriptors for which IPFreeBuff releases memory.

Return value

None

Remarks

If a firewall-hook driver previously created a chain of buffer descriptors and called the IPAllocBuff function to allocate memory for each buffer in each descriptor, the firewall-hook driver should call IPFreeBuff to release the memory for the chain.
