		int	major,
		int	minor,
		const std::string &	perm
	)

void lxcpp::CGroup::assignGroup ( pid_t pid )

inherited

Equivalent of: echo pid > mSubsys_path/mName/cgroup.procs

void lxcpp::CGroup::assignPid ( pid_t pid )

inherited

Assign single process to this cgroup (will be removed from previous cgroup automatically).

Equivalent of: echo pid > mSubsys_path/mName/tasks

void lxcpp::CGroup::create ( )

inherited

Create cgroup directory.

Equivalent of: mkdir subsys.path / mName

		int	major,
		int	minor,
		const std::string &	perm

bool lxcpp::CGroup::exists ( ) const

inherited

Check if cgroup exists.

Returns: true if cgroup path (subsys.path / mName) exists

CGroup lxcpp::CGroup::getCGroup	(	const std::string &	subsys,
		pid_t	pid
	)

staticinherited

Get cgroup of process pid in given subsystem.

std::string lxcpp::CGroup::getCommonValue ( const std::string & param ) const

inherited

Get common 'cgroup' paramter.

Equivalent of: cat mSubsys_path/mName/cgroup.param

std::vector< pid_t > lxcpp::CGroup::getPids ( ) const

inherited

Get list of pid assigned to this group.

Equivalent of: cat mSubsys_path/mName/tasks

std::string lxcpp::CGroup::getValue ( const std::string & param ) const

inherited

Get cgroup parameter.

Equivalent of: cat mSubsys_path/mName/mSubsys_name.param

std::vector< DevicePermission > lxcpp::DevicesCGroup::list ( )

void lxcpp::CGroup::setCommonValue	(	const std::string &	param,
		const std::string &	value
	)

inherited

Equivalent of: echo value > mSubsys_path/mName/cgroup.param

void lxcpp::CGroup::setValue	(	const std::string &	param,
		const std::string &	value
	)

inherited

Set cgroup parameter to value (name validity depends on subsystem).

Equivalent of: echo value > mSubsys_path/mName/mSubsys_name.param
