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 );

初始化的值object默認的原子對象desired。不是原子的功能是：從另一個線程的並發訪問，甚至可以通過一個原子操作，是數據爭用.

Original:

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.

obj是預設構造的，該行為是未定義.

Original:

If obj was not default-constructed, the behavior is undefined.

如果這個函數被調用兩次在同一obj，該行為是未定義.

Original:

If this function is called twice on the same obj, the behavior is undefined.

注釋

如果兼容不需要提供此函數是與C的兼容性，std::atomic可以通過他們的非默認構造函數初始化.

Original:

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