Functions

func Chtimes added in v1.9.0

func Chtimes(name string, atime time.Time, mtime time.Time) error

Chtimes changes the access time and modified time of a file at the given path

func CreateEvent added in v1.8.0

func CreateEvent(eventAttributes *syscall.SecurityAttributes, manualReset bool, initialState bool, name string) (handle syscall.Handle, err error)

CreateEvent implements win32 CreateEventW func in golang. It will create an event object.

func IsAbs added in v1.9.0

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 LUtimesNano

func LUtimesNano(path string, ts []syscall.Timespec) error

LUtimesNano is not supported on platforms other than linux, freebsd and darwin.

func Lgetxattr

func Lgetxattr(path string, attr string) ([]byte, error)

Lgetxattr is not supported on platforms other than linux.

func Lsetxattr

func Lsetxattr(path string, attr string, data []byte, flags int) error

type MemInfo added in v1.4.0

type MemInfo struct {
	// Total usable RAM (i.e. physical RAM minus a few reserved bits and the
	// kernel binary code).
	MemTotal int64

	// Amount of free memory.
	MemFree int64

	// Total amount of swap space available.
	SwapTotal int64

	// Amount of swap space that is currently unused.
	SwapFree int64
}

MemInfo contains memory statistics of the host system.

func ReadMemInfo added in v1.4.0

func ReadMemInfo() (*MemInfo, error)
