Functions

func NewBridgeFileHandle

func NewBridgeFileHandle(fd int) fs.FileHandle

NewBridgeFileHandle creates a FileHandle out of a file descriptor. All operations are implemented. When using the Fd from a *os.File, call syscall.Dup() on the Fd, to avoid os.File's finalizer from closing the file descriptor.

func NewBridgeNode

func NewBridgeNode(n *BridgeNode) fs.InodeEmbedder

func NewBridgeRoot

func NewBridgeRoot(rootPath string, NewNode func(rootData *bridgeRoot) fs.InodeEmbedder, GetRealPath func(nodePath string) string) (fs.InodeEmbedder, error)

NewBridgeRoot returns a root node for a loopback file system whose root is at the given root. This node implements all NodeXxxxer operations available.
