NAME
    GetCurrentDirName -- returns the current directory name (V36)

FUNCTION
    Extracts the current directory name from the CLI structure and puts it

    the call (with IoErr() == ERROR_OBJECT_WRONG_TYPE);

INPUTS
    buf     - Buffer to hold extracted name
    len     - Number of bytes of space in buffer

RESULT
