boost::process::v1::system
// In header: <boost/process/v1/system.hpp> template<typename ... Args> int system(Args &&... args);
Launches a process and waits for its exit. It works as std::system, though it allows all the properties boost.process provides. It will execute the process and wait for it's exit; then return the exit_code.
int ret = system("ls");
