int compare(const path& p) const noexcept;

Returns:

• (1.1)

  Let rootNameComparison be the result of this->root_name().native().compare(p.root_name().native()). If rootNameComparison is not 0, rootNameComparison.

• (1.2)

  Otherwise, if !this->has_root_directory() and p.has_root_directory(), a value less than 0.

• (1.3)

  Otherwise, if this->has_root_directory() and !p.has_root_directory(), a value greater than 0.

• (1.4)

  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.

• (1.5)

  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.

• (1.6)

  Otherwise, 0.
