int compare(const path& p) const noexcept;
Returns:
  • Let rootNameComparison be the result of this->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, if this->has_­root_­directory() and !p.has_­root_­directory(), a value greater than 0.
  • Otherwise, if native() for the elements of this->relative_­path() are lexicographically less than native() for the elements of p.relative_­path(), a value less than 0.
  • Otherwise, if native() for the elements of this->relative_­path() are lexicographically greater than native() for the elements of p.relative_­path(), a value greater than 0.
  • Otherwise, 0.
