Constructor & Destructor Documentation

proc_t() [1/3]

proc::proc_t::proc_t ( proc_t && )

default

Defaulted move constructor for the generated type.

proc_t() [2/3]

proc::proc_t::proc_t ( )

default

Default constructor for the generated type.

proc_t() [3/3]

proc::proc_t::proc_t ( boost::process::v1::environment && env, std::vector< ctx_t > && apps )

inline

Construct a process manager.

Parameters

env	Environment used when launching processes.
apps	Application launch contexts.

Member Function Documentation

execute()

int proc::proc_t::execute	(	int	app_id,
		std::shared_ptr< rtsp_stream::launch_session_t >	launch_session )

Launch the configured application process.

Parameters

app_id	App ID.
launch_session	Launch session.

Returns

Process exit code or launch error status.

get_app_image()

std::string proc::proc_t::get_app_image

(

int

app_id

)

Get app image.

Parameters

app_id

App ID.

Returns

Validated image path for the requested application.

get_apps() [1/2]

std::vector< ctx_t > & proc::proc_t::get_apps

(

)

Return the configured applications.

Returns

Mutable application list owned by the process manager.

get_apps() [2/2]

const std::vector< ctx_t > & proc::proc_t::get_apps

(

)

const

Return the configured applications.

Returns

Immutable application list owned by the process manager.

get_last_run_app_name()

std::string proc::proc_t::get_last_run_app_name

(

)

Get last run app name.

Returns

Name of the most recently launched application.

operator=()

proc_t & proc::proc_t::operator= ( proc_t && )

default

Defaulted move assignment for the generated type. * *.

• Returns

  This instance.

running()

int proc::proc_t::running

(

)

Returns

_app_id if a process is running, otherwise returns 0

update_apps_and_env()

void proc::proc_t::update_apps_and_env

(

proc_t &&

other

)

Update the cached app list and environment without disturbing running process state.

This replaces only the application configuration data (_apps and _env) from a newly parsed proc_t, preserving the current _app_id, _process, _process_group, and other fields that track an in-flight streaming session.

Parameters

other

The newly parsed proc_t whose apps and env will be moved into this instance.
