Subject Problem with WriterAppender
Date Mon, 10 Jan 2005 09:11:33 GMT


                I am facing a problem with the WriterAppender. I am
developing a custom appender class derived from WriterAppender class.  I
have initialized the custom appender class as follows:

                log4cxx::LayoutPtr layout(new log4cxx::PatternLayout(""));

       istringstream in_bis(ios_base:: in | ios_base::out |

                          ios_base::app );

       std::ostream *os = new std::ostream(in_bis.rdbuf());

       CCustomLogClass *my = new CCustomLogClass (layout,os);

CCustomLogClass has been derived from WriterAppender. Then I added this
custom appender class to the root logger and called debug, info, error
function with some log strings on root logger. I have set the immediateFlush
variable of the custom appender class as FALSE.

To extract the logging information in my custom appender class I have
written the following code:

       std::string str(10u,' ');

       std::stringbuf *pStream = new std::stringbuf;



I tried to get the logging string from str.c_str() function. But this
function was always returning NULL. Can anybody tell what else need to be
done to extract logging string or I am doing something wrong here.
