C ++ proc_open analogue

Question

There's a handy function in PHP called proc_open. It could be used to call an executable, opening its stdin, stdout and stderr as pipes.

Is there a good cross-platform version of this function in C++? The only googlable thing is this tutorial for Windows (though code from it just hangs).

Answer 1

You could probably get 'somewhere' with

• popen (http://linux.die.net/man/3/popen)

• pstreams library (POSIX process control) - I have no prior experience with this, but it looks solid and was written by Jonathan Wakely

• Boost Process (http://www.highscore.de/boost/process/, not in boost yet)

  • See also How to bind program termination with end-of-stream in Boost.Process 0.5?
  • and output with boost process library in c++

• Poco::Process launch (http://www.appinf.com/docs/poco/Poco.Process.html#13423)

  static ProcessHandle launch(
     const std::string & command,
      const Args & args,
      Pipe * inPipe,
      Pipe * outPipe,
      Pipe * errPipe
  );
