bool operator==( const locale& other ) const;	(1)
bool operator!=( const locale& other ) const;	(2)	(until C++20)

Tests two locales for equality. Named locales are considered equal if their names are equal. Unnamed locales are considered equal if they are copies of each other.

The != operator is synthesized from operator==.

(since C++20)

Parameters

other

-

a std::locale object to compare

Return value

1) true if other is a copy of *this or has an identical name, false otherwise.

2) false if other is a copy of *this or has an identical name, true otherwise.
