In order to overcome the burden of writing the manual reference counting, Apple introduced ARC. In the next section, we'll look at what this compiler feature can do, in order to provide efficient memory management.目录 上一章 下一章首页...

Once the current thread (Thread A) has decremented the reference count, Thread B could come in and free theArcInner. The problem becomes apparent when you look at the implementation offetch_sub: pubfnfetch_sub(&self,val:$int_type,order:Ordering)-> $int_type{unsafe{atomic_sub(self.v.get...
If the pointer list of this memory record is now empty, then the method200signals a memory leak (208). That is, if there are no longer any pointers that reference the memory in question, then a memory leak has occurred. Thus, if the pointer p is the only pointer in the pointer list...
