    ufusr_ask_unload is invoked immediately following the completion of ufusr
8 x3 h2 `+ r7 p& D    (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
    UF_UNLOAD_UG_TERMINATE, the ufusr_cleanup is called right before the dll is
    unload when NX is terminating.  To prove to yourself that this works, set
    the environment variable UGII_KEEP_SYSTEM_LOG=1 so that the syslog will not
    automatically be cleaned up when NX terminates.  Start NX.  Use Help-> NX
    Log File and make a note of the full path to the syslog which will be shown
    as its own first line.  Run the dll built from this code (nothing noticable

入口函数 改成 ufusr_cleanup

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
