operator==operator!=

 

bool operator==( const memory_resource& a, const memory_resource& b ) noexcept;	(1)	(library fundamentals TS)
bool operator!=( const memory_resource& a, const memory_resource& b ) noexcept;	(2)	(library fundamentals TS)

Compares the memory_resources a and b for equality. Two memory_resources compare equal if and only if memory allocated from one memory_resource can be deallocated from the other and vice versa.

Return value

1) &a == &b || a.is_equal(b)

2) !(a == b)

is_equal

compare for equality with another memory_resource (public member function)
