Defined in header <regex>

template< class BidirIt, class Alloc >
bool operator==( match_results<BidirIt,Alloc>& lhs,
                 match_results<BidirIt,Alloc>& rhs );

(1)

(since C++11)

template< class BidirIt, class Alloc >
bool operator!=( match_results<BidirIt,Alloc>& lhs,
                 match_results<BidirIt,Alloc>& rhs );

(2)

(since C++11)

Compares two match_results objects.

Two match_results are equal if the following conditions are met:

neither of the objects is ready, or
both match results are ready and the following conditions are met:
lhs.empty() and rhs.empty(), or
!lhs.empty() and !rhs.empty() and the following conditions are met:
- lhs.prefix() == rhs.prefix()
- std::equal(lhs.begin(), lhs.end(), rhs.begin())
- lhs.suffix() == rhs.suffix()

1) Checks if lhs and rhs are equal.

2) Checks if lhs and rhs are not equal.

lhs, rhs	-	match results to compare
Type requirements
- `BidirIt` must meet the requirements of `BidirectionalIterator`.
- `Alloc` must meet the requirements of `Allocator`.

1) true if lhs and rhs are equal, false otherwise.

2) true if lhs and rhs are not equal, false otherwise.

(none).
