A pointer to void can be converted to or from a pointer to any type, without restriction or loss of information. If the result is converted back to the original type, the original pointer is recovered.If a pointer is converted to another pointer with the same type but having different or...
1.void pointer can point to any data type, that is, any data type of pointer can assign to void pointer; E.G.: int *pint; pvoid = pint; //but not pint = pvoid if you want to assign pvoids to other types of pointer, you need to force type conversions such as:pint = (int*...

最近学习多线程,写Demo程序时,遇到一个编译器告警,就是在用 pthread_join 函数获取线程返回状态值时,出现 -Wpointer-to-int-cast 告警。下面来看一下具体是啥问题 原Demo 程序如下: #include<stdio.h>#include<stdlib.h>#include<assert.h>#include<pthread.h>void*func_1(void*);void*func_2(void...

staticnativevoidread(Pointer pointer,longbaseaddr,longoffset,byte[] buf,intindex,intlength); 可以看到它是一个真正的native方法,用来读取一个指针对象。 除了Byte数组之外,Pointer还提供了很多其他类型的读取方法。 又读取就有写入,我们再看下Pointer是怎么写入数据的: ...
}publicclassTestSingleton {publicstaticvoidmain(String[] args) { Singleton s=Singleton.getInstance(); System.out.println(s.getID()); } } 在这个例子中,我们声明了一个Singleton类的静态实例。该实例在该getInstance方法内最多初始化一次。注意使用null启用唯一实例创建的值。
