Constants

const MaxNameLen = 4096

MaxNameLen is the maximum length of the name of a file descriptor being sent using SendFile. The name of the file handle returned by RecvFile will never be larger than this value.

Functions

func RecvFile

func RecvFile(socket *os.File) (_ *os.File, Err error)

RecvFile waits for a file descriptor to be sent over the given AF_UNIX socket. The file name of the remote file descriptor will be recreated locally (it is sent as non-auxiliary data in the same payload).

func SendFile

func SendFile(socket *os.File, file *os.File) error

SendFile sends a file over the given AF_UNIX socket. file.Name() is also included so that if the other end uses RecvFile, the file will have the same name information.

func SendRawFd

func SendRawFd(socket *os.File, msg string, fd uintptr) error

SendRawFd sends a specific file descriptor over the given AF_UNIX socket.
