I don't know if that helps the OP, but it's certainly an improvement over mine! Thanks. -- Early On Wed, May 13, 2009 at 3:11 AM, Christopher Currie <christopher@currie.com>wrote:

Basically, you need to create a streambuf class that calls PySys_WriteStdout() inside your_streambuf_class::sync().
It's probably fairly straightforward to do this using Boost.Iostreams, by creating a model of Sink:
include <Python.h>
#include <algorithm> // min #include <iosfwd> // streamsize #include <boost/iostreams/categories.hpp> // sink_tag #include <boost/iostreams/stream.hpp> // stream #include <boost/format.hpp> // format
class pysys_stdout_sink { public: typedef char char_type; typedef boost::iostreams::sink_tag category;
std::streamsize write( const char* s, std::streamsize n ) { // PySys_WriteStdout truncates to 1000 chars static const std::streamsize MAXSIZE = 1000;
std::streamsize written = std::min( n, MAXSIZE ); PySys_WriteStdout( (boost::format("%%.%1%s") % written).str().c_str(), s );
return written; } };
boost::iostreams::stream<pysys_stdout_sink> pysys_stdout;
int main() { Py_Initialize(); pysys_stdout << "Hello, Python world!\n"; }
