FreeIprBuff function

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

The FreeIprBuff releases memory for the buffer of a single descriptor.

Syntax

VOID FreeIprBuff(
  _In_ IPRcvBuf *pRcvBuf
);

Parameters

  • pRcvBuf [in]
    Pointer to an IPRcvBuf structure that contains a pointer to a buffer that represents the memory to be released.

Return value

None

Remarks

If a firewall-hook driver previously called the IPAllocBuff function to allocate memory for a buffer that is contained in a buffer descriptor, the firewall-hook driver should call FreeIprBuff to release the memory for that buffer.

Requirements

Target platform

Desktop

Header

Ipfirewall.h (include Ipfirewall.h)

Library

Tcpip.lib
