Function template async_execute

boost::process::v2::async_execute — Execute a process asynchronously.

Synopsis

// In header: <boost/process/v2/execute.hpp>


template<typename Executor = net::any_io_executor, 
         Token WaitHandler = net::default_completion_token_t<Executor> > 
  auto async_execute(basic_process< Executor > proc, 
                     WaitHandler && handler = net::default_completion_token_t< Executor >());

Description

This function asynchronously for a process to complete.

Cancelling the execution will signal the child process to exit with the following interpretations:

cancellation_type::total -> interrupt
cancellation_type::partial -> request_exit
cancellation_type::terminal -> terminate

It is to note that async_execute will us the lowest selected cancellation type. A subprocess might ignore anything not terminal.
