一、C 风格(C-style)强制转型如下: (T) expression // cast expression to be of type T 函数风格(Function-style)强制转型使用这样的语法: T(expression) // cast expression to be of type T 这两种形式之间没有本质上的不同,它纯粹就是一个把括号放在哪的问题。我把这两种形式称为旧风格(old-style)...
I'm still think about some safe conversion of that pointers and wrote little code that make some conversions using void pointer and return void from function. then is static_cast conversion to needed format. I was think about that void, because it can handle anything, if you don't kn...
今天在编写多线程程序的时候,编译过程中出现了如下错误: thread.c: In function ‘main’: thread.c:38:57: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] 后来google了,受这个问题解决的启发http://stackoverflow.com/questions/9251102/warning-cast-to-pointer-from-integ...

蓝图中的cast to,尝试检查发出转换的对象是否为被转换的特定对象,举例子就是创建了一个特殊的蓝图,其中包含了许多的自定义功能,我们想要在其他的蓝图中调用这个自定义蓝图的功能。 我们可以用get player character节点在其他蓝图中对玩家角色昌盛影响,但是没有办法使用自定义蓝图中的功能,是因为我们获取的是玩家角色(父...
A pointer to a data object or to a function (but not a pointer to member) can be converted to any integer type large enough to contain it. (Typelongis always large enough to contain a pointer value on the architectures supported by the C++ compiler.) When converted back to the original...
