Types

type FileHandle

type FileHandle struct {
	// contains filtered or unexported fields
}

func NewFileHandle

func NewFileHandle(inode *inode.FileInode) (fh *FileHandle)

func (*FileHandle) Destroy

func (fh *FileHandle) Destroy()

Destroy any resources associated with the handle, which must not be used again.

func (*FileHandle) Inode

func (fh *FileHandle) Inode() *inode.FileInode

Inode returns the inode backing this handle.

func (*FileHandle) Lock

func (fh *FileHandle) Lock()

func (*FileHandle) Read

func (fh *FileHandle) Read(
	ctx context.Context,
	dst []byte,
	offset int64) (n int, err error)

Equivalent to locking fh.Inode() and calling fh.Inode().Read, but may be more efficient.

LOCKS_REQUIRED(fh) LOCKS_EXCLUDED(fh.inode)

func (*FileHandle) Unlock

func (fh *FileHandle) Unlock()
