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.
