std::pmr::memory_resource
Defined in header <memory_resource>
bool operator == ( const std:: pmr :: memory_resource & a,
const std:: pmr :: memory_resource & b ) noexcept ;
(1) (since C++17)
bool operator ! = ( const std:: pmr :: memory_resource & a,
const std:: pmr :: memory_resource & b ) noexcept ;
(2) (since C++17)
(until C++20)

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

The != operator is synthesized from operator== .

(since C++20)

Return value

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