# std::atomic::load

From cppreference.com
< cpp‎ | atomic‎ | atomic

|  | (since C++11)
T load( std::memory_order order = std::memory_order_seq_cst ) const; |  |
T load( std::memory_order order = std::memory_order_seq_cst ) const volatile; |  |

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.

### [edit] Parameters

order | - | memory order constraints to enforce

### [edit] Return value

The current value of the atomic variable.

### [edit] Exceptions

`noexcept` specification:
noexcept
