Function template async_system

boost::process::v1::async_system

Synopsis

// In header: <boost/process/v1/async_system.hpp>


template<typename ExitHandler, typename ... Args> 
  unspecified async_system(boost::asio::io_context & ios, 
                           ExitHandler && exit_handler, Args &&... args);

Description

This function provides an asynchronous interface to process launching.

It uses the same properties and parameters as the other launching function, but is similar to the asynchronous functions in boost.asio

It uses asio::async_result to determine the return value (from the second parameter, exit_handler).

	Note
	This function does not allow custom error handling, since those are done through the `exit_handler`.

Parameters:

`ios`	A reference to an io_context
`exit_handler`	The exit-handler for the signature `void(boost::system::error_code, int)`
