Description#

```
template<class T>
void atomic_add(T* const ptr_to_value, const T value);
```
Atomically executes *ptr_to_value += value.
- ptr_to_value: address of the to be updated value.
- value: value to be added.
```
template<class T>
void atomic_and(T* const ptr_to_value, const T value);
```
Atomically executes *ptr_to_value &= value.
- ptr_to_value: address of the to be updated value.
- value: value with which to combine the original value.
```
template<class T>
void atomic_assign(T* const ptr_to_value, const T value);
```
Atomically executes *ptr_to_value = value.
- ptr_to_value: address of the to be updated value.
- value: new value.
```
template<class T>
void atomic_decrement(T* const ptr_to_value);
```
Atomically executes (*ptr_to_value)-- or calls atomic_fetch_sub(ptr_to_value, T(-1)).
- ptr_to_value: address of the to be updated value.
```
template<class T>
void atomic_increment(T* const ptr_to_value);
```
Atomically executes (*ptr_to_value)++ or calls atomic_fetch_add(ptr_to_value, T(1)).
- ptr_to_value: address of the to be updated value.
```
template<class T>
void atomic_max(T* const ptr_to_value, const T value);
```
Atomically executes if (value > *ptr_to_value) *ptr_to_value = value.
- ptr_to_value: address of the to be updated value.
- value: value which to take the maximum with.
```
template<class T>
void atomic_min(T* const ptr_to_value, const T value);
```
Atomically executes if (value < *ptr_to_value) *ptr_to_value = value.
- ptr_to_value: address of the to be updated value.
- value: value which to take the minimum with.
```
template<class T>
void atomic_or(T* const ptr_to_value, const T value);
```
Atomically executes *ptr_to_value |= value.
- ptr_to_value: address of the to be updated value.
- value: value with which to combine the original value.
```
template<class T>
void atomic_sub(T* const ptr_to_value, const T value);
```
Atomically executes *ptr_to_value -= value.
- ptr_to_value: address of the to be updated value.
- value: value to be subtracted.
