NX二次开发-ufusr和ufsta等用户入口使用说明
作者：互联网
- 版本
NX9+VS2012
- 用户出口(入口)介绍
这段内容是从书上抄的
用户出口(User Exit)是NXOpen中的一个重要概念。NX在运行过程中某些特定的位置存在规定的出口，当进程执行到这些出口时，NX会自动检查用户是否在此处已定义了
指向内部程序位置的环境变量；若没有定义，则以NX默认的方式继续运行下去；若已定义，则从该处自动运行用户定制的应用程序。利用不同的User Exit，可使用户定制
的应用程序在NX运行到特定点时被自动执行。每个User Exit都有唯一的出口名称，以便用户在子程序中调用，不同的User Exit使用不同的出口函数，最常用的User Exit是
ufsta()与ufusr()，ufsta()是NX菜单启动时的User Exit，ufusr()是直接激活的User Exit。通常情况下，User Exit函数的参数和返回值都相同，User Exit函数的定义如下：
void entry_point(char *parm, int *returnCode, int rlen);
其中parm和returnCode是输出参数，rlen是指参数parm的长度，由NX系统自动处理。
- 官方文档上的说明
- 常用的两个入口函数例子
- ufusr()
官方有一个example例子，我们编译执行去看一下

我们二次开发最常用的入口函数就是ufusr()
执行ufusr有两种方式，
1.是直接挂到菜单栏上，从菜单点击下载。
2.是ctrl+u去执行dll
在用向导创建NX项目的时候，选择ufusr()
ctrl+u方式调用

打断点调试，查看传入的参数
通过这个就可以做点击不同的Button按钮传入不同的ID来判断字符串参数调用执行不同的函数功能。
来实现一个dll，点击不同button按钮执行不同功能。
- ufsta()
这个也是我们做二次开发经常用到的入口函数，主要是用UDO的时候要用到这个入口，当然还有一些其他需求也会用到。
比如这个例子NX二次开发-自动将NX标题设置为prt路径
与ufusr()需要点击菜单按钮或者ctrl+u调用才会被执行加载有所不同，ufusr()当NX启动时就被激活执行函数中的内容了。
在用向导创建NX项目的时候，选择ufsta()
编译出来的dll，直接放到二次开发文件夹startup里，都不需要挂菜单，启动ug就会自动加载了。

- 其他的入口函数例子
先贴一个书上的截图
这些User Exit的实现方式如下：在配置文件D:\Program Files\Siemens\NX 9.0\UGII\ugii_env_ug.dat中找到User Exit环境变量，
去掉环境变量左边的注释符"#"，然后按照"环境变量=DLL全路径"格式进行修改，最后在应用开发程序中添加该User Exit出口函数
并编写代码。编译通过后触发User Exit即可执行用户应用程序。
ufget()

*注意事项
如果"*returnCode = 1"，系统只执行NX用户在入口函数中定义的功能。
如果"*returnCode = 2"，系统在执行完用户功能后还要执行NX原打开文件的功能。
这些API帮助上面都有说明。
