template<class BidirectionalIterator, class Allocator> bool operator==(const match_results<BidirectionalIterator, Allocator>& m1, const match_results<BidirectionalIterator, Allocator>& m2);
Returns: true if neither match result is ready, false if one match result is ready and the other is not.
If both match results are ready, returns true only if
m1.empty() && m2.empty(), or
!m1.empty() && !m2.empty(), and the following conditions are satisfied:
m1.prefix() == m2.prefix(),
m1.size() == m2.size() && equal(m1.begin(), m1.end(), m2.begin()), and
m1.suffix() == m2.suffix().
[Note 1:
The algorithm equal is defined in [algorithms].
