func MkExclDir

func MkExclDir(stem string) (name string, err error)

MkExclDir creates a new directory with the condition that the directory did not exist prior to this call.

Stem is the desired name of the directory. The actual directory that is created might have numeric suffixes in its name which is the first return value.

func OpenExclFile

func OpenExclFile(stem, ext string) (file *os.File, err error)

OpenExclFile creates a new file for writing with the condition that the file did not exist prior to this call.

The first string should be the stem of the filename, the second the extension. If filename is "hello world.txt" then the stem is "hello world", ext is ".txt". See os.O_EXCL. Caller is responsible for closing the file upon a successful return.
