Functions ¶

func AttachLoopDevice ¶

func AttachLoopDevice(sparseName string) (loop *os.File, err error)

AttachLoopDevice attaches the given sparse file to the next available loopback device. It returns an opened *os.File.

func FindLoopDeviceFor ¶

func FindLoopDeviceFor(file *os.File) *os.File

FindLoopDeviceFor returns a loopback device file for the specified file which is backing file of a loop back device.

func SetCapacity ¶

func SetCapacity(file *os.File) error

SetCapacity reloads the size for the loopback device.
