    ufusr_ask_unload is invoked immediately following the completion of ufusr
    (or ufsta when the dll is run from a startup folder) to find out when you
    want the dll to be unloaded.  If ufusr_ask_unload returns

请问这个函数是怎么用的？有什么用？

  F$ ?( G7 z+ t; d4 k* G入口函数 改成 ufusr_cleanup
* l! m: I/ q4 Z
% Y1 c: @/ R! X3 k+ ?# Z% G意思是 NX 程序退出后，你可以做些事情 ，具体做啥可以自己写，就是个入口

licxsw

测试了 ufusr_cleanup入口处复制文件到指定目录下，不成功
