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

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

#include <boost/process.hpp>

#include <string>
#include <iostream>

using namespace boost::process;

int main()
{
    ipstream pipe_stream;
    child c("gcc --version", std_out > pipe_stream);

    std::string line;

    while (pipe_stream && std::getline(pipe_stream, line) && !line.empty())
        std::cerr << line << std::endl;

    c.wait();
}
