Functions

func ListenAndServe

func ListenAndServe(family, addr string, handler Handler) error

ListenAndServe listens on the given address/family and then calls Serve with handler to handle incoming requests.

func Serve

func Serve(l net.PacketConn, handler Handler)

Serve accepts incoming TFTP read requests on the listener l, creating a new service goroutine for each. The service goroutines use handler to get a byte stream and send it to the client.

Types

type Handler

type Handler func(path string, clientAddr net.Addr) (io.ReadCloser, error)

A Handler provides the bytes for a file.

func Blob

func Blob(b []byte) Handler

Blob returns a handler that serves b for all paths and clients.
