### Operations on atomic types <a id="depr.atomics.types.operations">[[depr.atomics.types.operations]]</a>

|

+
``` cpp
|
| 4 |
+
#define ATOMIC_VAR_INIT(value) see below
|
| 5 |
+
```
|
| 6 |
+
|
| 7 |
+
The macro expands to a token sequence suitable for constant
|
| 8 |
+
initialization of an atomic variable of static storage duration of a
|
| 9 |
+
type that is initialization-compatible with `value`.
|

+
|
| 11 |
+
[*Note 1*: This operation may need to initialize locks. — *end note*]
|
| 12 |
+
|
| 13 |
+
Concurrent access to the variable being initialized, even via an atomic
|
| 14 |
+
operation, constitutes a data race.

+
[*Example 1*:
|
| 17 |
+
|
| 18 |
+
``` cpp
|
| 19 |
+
atomic<int> v = ATOMIC_VAR_INIT(5);
|

```
