Function Documentation

calculate_app_id()

std::tuple< std::string, std::string > proc::calculate_app_id	(	const std::string &	app_name,
		std::string	app_image_path,
		int	index )

Calculate a stable id based on name and image data.

Returns

Tuple of id calculated without index (for use if no collision) and one with.

init()

std::unique_ptr< platf::deinit_t > proc::init

(

)

Initialize proc functions.

Returns

Unique pointer to deinit_t to manage cleanup

terminate_process_group()

void proc::terminate_process_group	(	boost::process::v1::child &	proc,
		boost::process::v1::group &	group,
		std::chrono::seconds	exit_timeout )

Terminates all child processes in a process group.

Parameters

proc	The child process itself.
group	The group of all children in the process tree.
exit_timeout	The timeout to wait for the process group to gracefully exit.
