              <tr>
                <td align="left">

        <p>
The <code class="function">ATOMIC_VAR_INIT</code> macro expands to a token sequence suitable for initializing an atomic 
object of a type that is initialization-compatible with value. An atomic object with automatic 
storage duration that is not explicitly initialized using <code class="function">ATOMIC_VAR_INIT</code> is initially in an 
indeterminate state; however, the default (zero) initialization for objects with static storage 
duration is guaranteed to produce a valid state.
        </p>
        <p>
This macro can only be used to initialize atomic 
objects that are declared in program scope in the global 
address space.
        </p>
        <p>
Concurrent access to the variable being initialized, even via an atomic operation, constitutes a 
data-race.
