bool test( std::memory_order order =
std::memory_order_seq_cst ) const volatile noexcept;
 (1) 
 (since C++20) 
std::memory_order_seq_cst ) const volatile noexcept;
bool test( std::memory_order order =
std::memory_order_seq_cst ) const noexcept;
 (2) 
 (since C++20) 
std::memory_order_seq_cst ) const noexcept;
Atomically reads the value of the *this and returns the value.
If order is one of std::memory_order_release and std::memory_order_acq_rel , the behavior is undefined.
