this can do it nicely.

+      PStreams allows you to run another program from your C++ application and
+      to transfer data between the two programs similar to shell pipelines.
+
+      In the simplest case, a PStreams class is like a C++ wrapper for the
+      POSIX.2 functions popen(3) and pclose(3), using C++ iostreams instead of
+      C's stdio library.
