func FMountat added in v1.1.4

func FMountat(dirfd uintptr, source, target, fstype string, flags uintptr, data string) error

FMountat performs mount from the provided directory.

func ForceRemoveAll added in v1.1.0

func ForceRemoveAll(path string) error

ForceRemoveAll on unix is just a wrapper for os.RemoveAll

func GetLocalListener

func GetLocalListener(path string, uid, gid int) (net.Listener, error)

func GetOOMScoreAdj added in v1.3.0

func GetOOMScoreAdj(pid int) (int, error)

GetOOMScoreAdj gets the oom score for a process

func GetOpenFds

func GetOpenFds(pid int) (int, error)

GetOpenFds returns the number of open fds for the process provided by pid

func GetSubreaper

func GetSubreaper() (int, error)

GetSubreaper returns the subreaper setting for the calling process

func GetSystemCPUUsage

func GetSystemCPUUsage() (uint64, error)

GetSystemCPUUsage returns the host system's cpu usage in nanoseconds. An error is returned if the format of the underlying file does not match.

Uses /proc/stat defined by POSIX. Looks for the cpu statistics line and then sums up the first seven fields provided. See `man 5 proc` for details on specific field information.

func SetOOMScore

func SetOOMScore(pid, score int) error

SetOOMScore sets the oom score for the provided pid

func SetSubreaper

func SetSubreaper(i int) error

SetSubreaper sets the value i as the subreaper setting for the calling process

func StatATimeAsTime added in v1.1.0

func StatATimeAsTime(st *syscall.Stat_t) time.Time

StatATimeAsTime returns st.Atim as a time.Time

func StatAtime

type Exit

type Exit struct {
	Pid    int
	Status int

Exit is the wait4 information from an exited process

func Reap

func Reap(wait bool) (exits []Exit, err error)
