Functions ¶

func AdjustOOMScore ¶

func AdjustOOMScore(pid, score int) error

AdjustOOMScore sets the oom score for the provided pid. If the provided score is out of range (-1000 - 1000), it is clipped to the min/max value.

Not implemented on Windows

func CreateSequential ¶

func CreateSequential(name string) (*os.File, error)

CreateSequential is deprecated.

Deprecated: use github.com/moby/sys/sequential.Create

func GetLocalListener ¶

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

GetLocalListener returns a Listernet out of a named pipe. `path` must be of the form of `\\.\pipe\<pipename>` (see https://msdn.microsoft.com/en-us/library/windows/desktop/aa365150)

func GetOOMScoreAdj ¶

func GetOOMScoreAdj(pid int) (int, error)

GetOOMScoreAdj gets the oom score for a process

Not implemented on Windows

func MkdirAll ¶

func MkdirAll(path string, _ os.FileMode) error

MkdirAll is a custom version of os.MkdirAll that is volume path aware for Windows. It can be used as a drop-in replacement for os.MkdirAll.

func MkdirAllWithACL ¶

func MkdirAllWithACL(path string, _ os.FileMode) error

MkdirAllWithACL is a custom version of os.MkdirAll modified for use on Windows so that it is both volume path aware, and to create a directory an appropriate SDDL defined ACL for Builtin Administrators and Local System.

func OpenFileSequential ¶

func OpenFileSequential(name string, flag int, perm os.FileMode) (*os.File, error)

OpenFileSequential is deprecated.

Deprecated: use github.com/moby/sys/sequential.OpenFile

func OpenSequential ¶

func OpenSequential(name string) (*os.File, error)

OpenSequential is deprecated.

Deprecated: use github.com/moby/sys/sequential.Open

func SetOOMScore ¶

func SetOOMScore(pid, score int) error

SetOOMScore sets the oom score for the process

Not implemented on Windows

func TempFileSequential ¶

func TempFileSequential(dir, prefix string) (f *os.File, err error)

TempFileSequential is deprecated.

Deprecated: use github.com/moby/sys/sequential.CreateTemp
