int compare(const path& p) const noexcept;

Returns:

• Let rootNameComparison be the result ofthis->root_name().native().compare(p.root_name().native()).
  If rootNameComparison is not 0,rootNameComparison.
• Otherwise, if!this->has_root_directory() and p.has_root_directory(), a value less than 0.
• Otherwise, ifthis->has_root_directory() and !p.has_root_directory(), a value greater than 0.
• Otherwise, ifnative() for the elements of this->relative_path() are lexicographically less thannative() for the elements of p.relative_path(), a value less than 0.
• Otherwise, ifnative() for the elements of this->relative_path() are lexicographically greater thannative() for the elements of p.relative_path(), a value greater than 0.
