CreateConstBuffer Method of the IFWXFirewall Interface

The CreateConstBuffer method creates a buffer object that wraps a user-supplied memory buffer.

Syntax

HRESULT CreateConstBuffer(
  [in]   BYTE* pBuffer,
  [in]   DWORD dwBufferLength,
  [out]  IFWXIOBuffer** pIOBuffer
);

Parameters

pBuffer: Pointer to the data buffer.
dwBufferLength: Length, in bytes, of the buffer pointed to by the pBuffer parameter.
pIOBuffer: Address of a variable that receives a pointer to the IFWXIOBuffer interface.

Return Value

This method returns S_OK if the call is successful; otherwise, it returns an error code.

Remarks

Use only when the data is known to be a constant and the buffer memory does not have to be freed. To create a buffer for data that is not constant, use the IFWXFirewall::CreateBuffer method.
