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
