在C ++中使用Boost的命名管道序列化对象

Question

I am attempting to serialize some EEG data from a command line application using the Boost library for the serialization and sending that serialized data over a named pipe to a user interface Form built in Visual Studio C++ 2010.

From the boost library tutorial I am able to serialize my data structure, and, http://www.boost.org/doc/libs/1_48_0/libs/serialization/doc/tutorial.html#simplecase

from this tutorial on Win32 named pipes, I can construct pipes and send text between applications. http://avid-insight.co.uk/joomla/component/k2/item/589-introduction-to-win32-named-pipes-cpp?tmpl=component&print=1

The boost library tutorial serializes for a text file:

std::ofstream ofs("filename");

// create class instance
const gps_position g(35, 59, 24.567f);

// save data to archive
{
    boost::archive::text_oarchive oa(ofs);
    // write class instance to archive
    oa << g;
    // archive and stream closed when destructors are called
}

I want to know what do I need to serialize to in order to send my data structure over a named pipe? The IOstream c++ library seems to always need a file to stream to/from? http://www.cplusplus.com/reference/iostream/

I don't want o serialize to a file and I am not sure what to serialize to? I would really appreciate it if you could tell me what I need to serialize to and it would be great if you could tell me whether another boost command will be required other than boost::archive:: text_oarchive , as I have been unable to find an alternative.

Thank you for your time! It is really appreciated!

(This question has been asked before: Serialize and send a data structure using Boost? , but the person was told not to use boost as for his simple data structure boost would have too much overhead, so it really is still floating.)

Thanks ForEveR, very simple, don't know how I missed it! :) The solution in context with the two tutorials posted above:

    const EEG_Info g(35, 59, 24.567f);
std::stringstream MyStringStream ;
boost::archive::text_oarchive oa(MyStringStream);
    // write class instance to archive
    oa << g;
// This call blocks until a client process reads all the data

string strData;
strData = MyStringStream.str(); 


DWORD numBytesWritten = 0;
result = WriteFile(
    pipe, // handle to our outbound pipe
    strData.c_str(), // data to send
    strData.length(), // length of data to send (bytes)
    &numBytesWritten, // will store actual amount of data sent
    NULL // not using overlapped IO
);
