NAME¶

std::atomic_flag::test - std::atomic_flag::test

Synopsis¶

bool test( std::memory_order order =
std::memory_order_seq_cst ) const volatile (1) (since C++20)
noexcept;
bool test( std::memory_order order = (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.

Parameters¶

order - the memory synchronization ordering
