void atomic_init( volatile A* obj, C desired ); | (since C11) |
Initializes the default-constructed atomic object obj with the value desired. The function is not atomic: concurrent access from another thread, even through an atomic operation, is a data race.
This is a generic function defined for all atomic object types A. The argument is pointer to a volatile atomic type to accept addresses of both non-volatile and volatile (e.g. memory-mapped I/O) atomic variables.C is the non-atomic type corresponding to A.
Parameters
| obj | - | pointer to an atomic object to initialize |
| desired | - | the value to initialize atomic object with |
Return value
(none).
