int compare(const path& p) const noexcept;
Returns:
  • A value less than 0, if native() for the elements of *this are lexicographically less than native() for the elements of p; otherwise,
  • a value greater than 0, if native() for the elements of *this are lexicographically greater than native() for the elements of p; otherwise,
  • 0.
Remarks: The elements are determined as if by iteration over the half-open range [begin(), end()) for *this and p.
int compare(const string_type& s) const int compare(basic_string_view<value_type> s) const;
Returns: compare(path(s)).
int compare(const value_type* s) const
Returns: compare(path(s)).
