如何在CBuilder中实现一个简单的鼠标钩子？(100分)

&nbsp;各位大虾：<br>&nbsp; 为何我在定义钩子过程函数时只能定义成int (_stdcall *)() 型的而不是<br>&nbsp;LRESULT CALLBACK MouseProc(int Code,WPARAM,LPARAM);型的？<br>&nbsp;

&nbsp;上一问题通过函数强制转换可以解决，但在定义共享数据段时又遇到了问题。我的定义方法如下：<br>在主函数头部：<br>#pragma data_seg("mydata")<br>HWND hHook=NULL;<br>&nbsp; &nbsp; &nbsp;.<br>&nbsp; &nbsp; &nbsp;.<br>&nbsp; &nbsp; &nbsp;.<br>#pragma data_seg()<br>在.def文件中定义如下：<br>SECTIONS mydata READ WRITE SHARED<br>结果在编译时出现如下提示错误：<br>Section mydata defined in .def file is empty<br>看来CBuilder 好象不支持data_seg的定义方式。<br>不知哪位高手可以赐教在CBuilder中定义共享数据段的方法？<br>在下万分感激！！！！

我只知在Delphi上怎么作。
