c – 类中的Typedef函数

我希望能够在类中包含我的typedef函数.但我找不到办法做到这一点.我需要扫描地址,所以我不能硬编码,因此我需要像这个SetCursorPosFunction =(_ SetCursorPos)(地址到函数)设置地址;

例：

class Cursor
{
public:

    typedef BOOL(__stdcall *_SetCursorPos) (int X, int Y);
    _SetCursorPos SetCursorPosFunction;
};

我想能够像这样调用Cursor :: SetCursorPosFunction(x,y)这个函数

我的意思的例子.

void Function()
{
    DWORD_PTR AddressToFunctionSetCourserPos = Find(....);
    Cursor::SetCursorPosFunction = (Cursor::_SetCursorPos)(AddressToFunctionSetCourserPos ); //In final version it is going to be in a separate function where i get all the functions i need (This find() function can not be looped or called often, it is going to create lag etc.).

    Cursor::SetCursorPosFunction(1, 1);

}

我得到错误：

fatal error LNK1120: 1 unresolved externals
error LNK2001: unresolved external symbol "public: static int (__cdecl* Cursor::SetCursorPosFunction)(int,int)" (?SetCursorPosFunction@Cursor@@2P6AHHH@ZEA)

将函数修改为静态将允许您使用它而无需首先实例化成员,如下所示：

class Cursor
{
public:
    typedef BOOL(__stdcall *_SetCursorPos) (int X, int Y);
    static _SetCursorPos SetCursorPosFunction;
};

Cursor :: SetCursorPosFunction(x,y)现在应该可以工作(先给它初始化).

您还需要在全局空间中初始化静态成员.像Cursor :: _ SetCursorPos Cursor :: SetCursorPosFunction = nullptr;应该管用.但要注意只在一个翻译单元中使用它.
