You're of course right. I've worked too long on this, so it all seems
obvious to me. I'll add some more detailed example in the documentation
as soon as I have the time. As for the previous example (since I can't
edit the mail):

pstream pipe; //iostream implementation with a pipe

//start the process
child c(
     "some_prog", //program name
     "--some-arg", //argument
     env["PATH"]+="C:/stuff", //add C:/stuff to the PATH-environment
     std_in < "data.csv", //redirect stdin to a file
     std_out > pipe, //redirect stdout to created pipe
     std_err > null, //redirect stderr to /dev/null
     start_dir="./bin");//start in ./bin

std::string data;
pipe >> data; //read a string from the pipe.

c.wait(); //wait for the program to exit
cout << c.exit_code() << endl;//print the return code
