Introduction

Boost.Process is a library to manage system processes. It can be used to:

create child processes
setup streams for child processes
communicate with child processes through streams (synchronously or asynchronously)
wait for processes to exit (synchronously or asynchronously)
terminate processes

Here's a simple example of how to start a program with Boost.Process:

#include\<boost/process.hpp\>#include\<string\>#include\<iostream\>usingnamespaceboost::process;intmain(){ipstreampipe\_stream;childc("gcc --version",std_out\>pipe\_stream);[std::string](http://en.cppreference.com/w/cpp/string/basic_string)line;while(pipe\_stream&&[std::getline](http://en.cppreference.com/w/cpp/string/basic_string/getline)(pipe\_stream,line)&&!line.empty())std::cerr\<\<line\<\<std::endl;c.wait();}
