Functions

func CreateSequential

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

CreateSequential creates the named file with mode 0666 (before umask), truncating it if it already exists. If successful, methods on the returned File can be used for I/O; the associated file descriptor has mode O_RDWR. If there is an error, it will be of type *PathError.

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 IsAbs

func IsAbs(path string) bool

IsAbs is a platform-specific wrapper for filepath.IsAbs. On Windows, golang filepath.IsAbs does not consider a path \windows\system32 as absolute as it doesn't start with a drive-letter/colon combination. However, in docker we need to verify things such as WORKDIR /windows/system32 in a Dockerfile (which gets translated to \windows\system32 when being processed by the daemon. This SHOULD be treated as absolute from a docker processing perspective.

func MkdirAll

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

MkdirAll implementation that is volume path aware for Windows.

func MkdirAllWithACL

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

MkdirAllWithACL is a wrapper for MkdirAll that creates a directory ACL'd for Builtin Administrators and Local System.

func OpenFileSequential

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

OpenFileSequential is the generalized open call; most users will use Open or Create instead. If there is an error, it will be of type *PathError.

func OpenSequential

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

OpenSequential opens the named file for reading. If successful, methods on the returned file can be used for reading; the associated file descriptor has mode O_RDONLY. If there is an error, it will be of type *PathError.

func SetOOMScore

func SetOOMScore(pid, score int) error

SetOOMScore sets the oom score for the process

Not implemented on Windows
