Types

type Cgroup

type Cgroup struct {
	HierarchyID    string
	ControllerList string
	GroupPath      string
}

Cgroup represents a linux cgroup.

func GetCgroups

func GetCgroups(pid int32, fs FileSystem) ([]Cgroup, error)

GetCGroups returns a slice of cgroups for pid using fs for filesystem calls.

The expected cgroup format is "hierarchy-ID:controller-list:cgroup-path", and this function will return an error if every cgroup does not meet that format.
