Re: Streaming wstring into log4cxx::StringBuffer

[Curt Arnold]

This code will be log4cxx 0.9.7 specific and will not work with the CVS 
HEAD or the forthcoming log4cxx 0.9.8 as StringBuffer is going away and 
log4cxx will be able handle both wchar_t* and char* requests.  If you 
want to stick with 0.9.7 and the form that you have, you need to write 
an insertion operator that converts the wide string to the current 
char* encoding and adds it to the StringBuffer, something like:

log4cxx::StringBuffer& operator<<(log4cxx::StringBuffer& oss, const 
wchar_t* str) {
     //   would need to call wcstombs or similar and insert into 
StringBuffer
}


With the CVS_HEAD
LOG4CXX_INFO(logger, std::wstring(L"BufferReader::Readstring, data :") 
+ v);

I'm using log4cxx 0.9.7 and I have read a wstring into v and want to 
output it to the log. I do like:
::log4cxx::StringBuffer oss;
oss << "BufferReader::Readstring, data : " << v.c_str();

However in the output I get
18845 [3209966400] INFO  whine  - BufferReader::ReadString, data : 
0x81f89cc

i.e. I get the pointer and not the string like I would hope. I have 
tried a few other methods, but with no luck.
How should I do to output a wstring?
