| _Bool atomic_is_lock_free( const volatile A* obj );

(since C11) | |
Determines if the atomic operations on all objects of the type A (the type of the object pointed to by obj) are lock-free. In any given program execution, the result of calling atomic_is_lock_free is the same for all pointers of the same type.
This is a generic function defined for all atomic object types.

[edit] Parameters
| obj | - | pointer to the atomic object to inspect |
[edit] Return value
true if the the operations on all objects of the type A are lock-free, false otherwise.
[edit] Notes
C11, as published, specified that this function is per-object, not per-type. This was corrected by DR 465.
