Functions

func File

func File(src, dest string, opt *Options) (written int64, err error)

File copies the file named in src to a file named in dest. It returns the number of bytes written and an error, if any. File uses buffered I/O and delegates to io.Copy to do the actual work. The behavior can be optionally influenced by setting options in opt.
