template< class OuterAlloc1, class OuterAlloc2, class... InnerAllocs > bool operator==( const scoped_allocator_adaptor<OuterAlloc1, InnerAllocs...>& lhs,                  const scoped_allocator_adaptor<OuterAlloc2, InnerAllocs...>& rhs ) noexcept;		(since C++11)
template< class OuterAlloc1, class OuterAlloc2, class... InnerAllocs > bool operator!=( const scoped_allocator_adaptor<OuterAlloc1, InnerAllocs...>& lhs,                  const scoped_allocator_adaptor<OuterAlloc2, InnerAllocs...>& rhs ) noexcept;		(since C++11)

Compares two scoped allocator adaptors. Two such allocators are equal if:

• lhs.outer_allocator() == rhs.outer_allocator(), and
• if sizeof...(InnerAllocs) > 0, lhs.inner_allocator() == rhs.inner_allocator().

Parameters

lhs, rhs

-

scoped allocator adaptors to compare

Return value

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

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