    REFIID riid, 
    void** ppvObject, 
    IMalloc* pMalloc
);

Arguments

• riid
  [in] The reference ID

• ppvObject

• pMalloc
  [in] An IMalloc implementation specified by the user. This argument can be Null.

Return Value

This function returns S_OK if no error is generated.

Remarks

This constructor is used to create the writer. If no IMalloc is provided, the default implementation of IMalloc is used.

The following code shows the declaration of an IXmlWriter object. The declaration and creation of an IStream object; and the call to CreateXmlWriter:

// This code is excerpted from XmlLiteNamespaceWriter1.cpp.
int _tmain(int argc, _TCHAR* argv[])
{
    HRESULT hr;
    CComPtr<IStream> pOutFileStream;
    CComPtr<IXmlWriter> pWriter;

    if (argc != 2)
    {
        printf("Usage: XmlLiteNamespaceWriter1.exe name-of-output-file\n");
        return 0;
    }

    //Open writeable output stream
    if (FAILED(hr = FileStream::OpenFile(argv[1], &pOutFileStream, TRUE)))
    {
        wprintf(L"Error creating file writer, error is %08.8lx", hr);
        return -1;
    }

    if (FAILED(hr = CreateXmlWriter(__uuidof(IXmlWriter),(void**) &pWriter, NULL)))
    {
        wprintf(L"Error creating xml writer, error is %08.8lx", hr);
        return -1;
    }

    if (FAILED(hr = pWriter->SetOutput(pOutFileStream)))
    {
        wprintf(L"Error setting output for writer, error is %08.8lx", hr);
        return -1;
    }
