static_point_cast 是一种用于智能指针类型间的编译时强制转换的工具,它的用法与 static_cast 类似,但专门用于智能指针。它不会在运行时进行检查,适用于你明确知道对象类型并且类型转换不会失败的场景。static_point_cast 主要用于在继承层次中进行从基类智能指针到派生类智能指针的转换。

Static Cast: The simplest cast that can be used is thestatic cast. It is a cast done atcompile time. It can call explicit conversion functions as well as perform implicit type conversions (such asconvertinganintto afloator apointerto avoid*). ...
可能是你的某个响应函数的原型，用了 UINT作为返回值，而原本需要LRESULT
