Atomically loads and returns the current value of the atomic variable. Memory is affected according to the value of order
.
order
must be one of std::memory_order_relaxed
, std::memory_order_consume
, std::memory_order_acquire
or std::memory_order_seq_cst
. Otherwise the behavior is undefined.
The volatile-qualified version is deprecated if | (since C++20) |
