Types

type File 

type File struct {
	*os.File
	// contains filtered or unexported fields
}

File implements vfs.File for the current target operating system.

func Open 

func Open(path string, mode os.FileMode) (*File, error)

func (*File) Lock 

func (f *File) Lock(exclusive, blocking bool) error

func (*File) MMap 

func (f *File) MMap(sz int) ([]byte, error)

func (*File) MUnmap 

func (f *File) MUnmap(b []byte) error

func (*File) Size 

func (f *File) Size() (int64, error)

func (*File) Stat 

func (f *File) Stat() (os.FileInfo, error)

func (*File) Sync 

func (f *File) Sync(flags vfs.SyncFlag) error

Sync uses FlushFileBuffers to flush all file buffers to disk. For more information about the operation executed check the FlushFileBuffers API docs1.

Depending on Windows+driver versions or system wide settings, FlushFileBuffers might not be reliable. While FlushFileBuffers flushes the OS disk cache, we require a FLUSH_CACHE to be executed and honored by the driver and the device. Otherwise we might suffer data loss and file corruption. Also see 2 and 3.

Enabling write caching on the disk 4 can disable the FLUSH_CACHE command, potentially leading to data loss and file corruption if the disk looses power.

Check 5, for why we don't want to use write through.

func (*File) Truncate 

func (f *File) Truncate(sz int64) error

func (*File) Unlock 

func (f *File) Unlock() error
