H A Datomics.md14 the [C11 memory model](https://en.cppreference.com/w/c/atomic/memory_order)
42 By default, C11 comes with two variants of each atomic "operation":
50 matching *seq_cst* atomic operations on your behalf.
97 (or `_Atomic volatile`), which allow for use of atomic
132 Qualifying atomic variables with `_Atomic` or even
141 atomic interfaces, but this header is considered obsolete
168 `os_atomic_store_wide` can be used to have access to atomic loads and store
