void atomic_init( volatile A* obj, C desired );
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 objects, and volatile semantic is preserved when applying this operation to volatile atomic objects.
C is the non-atomic type corresponding to
It is unspecified whether the name of a generic function is a macro or an identifier declared with external linkage. If a macro definition is suppressed in order to access an actual function (e.g. parenthesized like
(atomic_init)(...)), or a program defines an external identifier with the name of a generic function, the behavior is undefined.
