ext

The headers in process/ext provides features to obtain information about third part processes.

// Get the cmd line used to launche the process
template<typename Executor>
shell cmd(basic_process_handle<Executor> & handle, error_code & ec);
template<typename Executor>
shell cmd(basic_process_handle<Executor> & handle);
shell cmd(pid_type pid, error_code & ec);
shell cmd(pid_type pid);


// Get the current working directory of the process.
template<typename Executor>
filesystem::path cwd(basic_process_handle<Executor> & handle, error_code & ec);
template<typename Executor>
filesystem::path cwd(basic_process_handle<Executor> & handle)
filesystem::path cwd(pid_type pid, error_code & ec);
filesystem::path cwd(pid_type pid);


// Get the current environment of the process.
template<typename Executor>
env_view cwd(basic_process_handle<Executor> & handle, error_code & ec);
template<typename Executor>
env_view cwd(basic_process_handle<Executor> & handle)
env_view env(pid_type pid, error_code & ec);
env_view env(pid_type pid);


// Get the executable of the process.
template<typename Executor>
filesystem::path exe(basic_process_handle<Executor> & handle, error_code & ec);
template<typename Executor>
filesystem::path exe(basic_process_handle<Executor> & handle)
filesystem::path exe(pid_type pid, error_code & ec);
filesystem::path exe(pid_type pid);

Warning

The function may fail with "operation_not_supported" on some niche platforms.

Note	On windows overloads taking a HANDLE are also available.
