IFWXFirewall::CreateConstBuffer method

Applies to: desktop apps only

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 [in]
  Pointer to the data buffer.

• dwBufferLength [in]
  Length, in bytes, of the buffer pointed to by the pBuffer parameter.

• pIOBuffer [out]
  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.
