Rohini,

you can download the latest draft of Boost.Process from  
http://www.highscore.de/boost/gsoc2010/process.zip. This version provides  
stream behaviors to configure streams of a child process. Among others a  
stream behavior for named pipes is provided. You could use it like this:

named_pipe np("/tmp/mypipe");
stream_ends ends = np(input_stream);
... = ends.child.native();
... = ends.parent.native();

The parameter passed to named_pipe::operator()() tells the stream behavior  
if the child handle should be configured for input or output. stream_ends  
is basically a std:pair<handle, handle> without requiring developers to  
remember what the child and the parent handle is. And the method  
handle::native() (and handle::release()) can be used to get the file  
descriptor on Unix and the HANDLE on Windows.

HTH,
Boris
