Is there a C++ equivalent of Java's Process.getOutputStream()?

Question

Is there a way to get the stdin, stdout, and stderr streams of a process called by a C++ program, similar to Java's get*Stream() functions?  I know about C++'s system(...) call but the only way I'm able to get the called process' output is by piping it to a file and then reading it back in, which is not an option in this case.

There is no way to do that in standard C++, and it is not possible for preexisting processes.
You can do that using operating system specific system calls though, provided that it's your process that creates the other process.
For Microsoft Windows, see: http://msdn.microsoft.com/en-us/library/ms682499(VS.85).aspx
For POSIX systems (Unix, Linux, BSD, Mac OS), search for "popen".
May be there is a portable library that encapsulate several operating systems in a single API.
