clean_path (
    const char *path)

Synopsis

Returns a clean directory name; i.e. resolves the path, removes a trailing slash unless the name consists just of '/'; on a MS- DOS file system, cleans-up a directory name consisting of a disk specifier. The cleaned-up directory path is in a static area that is overwritten by each call.
