Defined in header
<atomic>

template< class T >
void atomic_init( std::atomic<T>* obj, T desired ); |

template< class T >
void atomic_init( volatile std::atomic<T>* obj, T desired ); |
(since C++11) | |
Initializes the default-constructed atomic object object
with the value desired
. The function is not atomic: concurrent access from another thread, even through an atomic operation, is a data race.
If obj
was not default-constructed, the behavior is undefined.
If this function is called twice on the same obj
, the behavior is undefined.

[edit] Notes
This function is provided for compatibility with C. If the compatibility is not required, std::atomic may be initialized through their non-default constructors.
