[lug] C++ libraries in Linux

Hi,

I believe you have memory leak in your example.  Once you do buf.str(), the
program owns the *char that is returned, unless it tells strstream otherwise,
which I forget how to do.  I believe you need to do it like:

char * s = buf.str();
rtnval = s;
delete [] s;
return rtnval;
