    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
6 s3 a$ o6 A$ ~. D2 L    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
/ E% ?1 S; d$ Q    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

: C- I; n4 e) s. l' t1 q请问这个函数是怎么用的？有什么用？

入口函数 改成 ufusr_cleanup
  d( e, p0 N3 M
5 `2 O9 O% c0 t# f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
