labview的深入探索----如何实现类似C的函数指针调用

作者：时间：2017-01-09 来源：网络

下面再定义一个CAL,类似上面的PROCESS

需要说明的是,上面的VI有一个输入参数是VI 参考,这个VI参考是严格数据类型的,相当于PROCESS函数中的函数指针,说明一下它的生成过程.

然后用浏览找到子VI,就可以直接使用了.
这样,CAL VI有三个输入参数,a,b,vi refnum和一个输出(返回值),相当于PROCESS函数.

看看它的具体调用过程.

上面CASE中用的是STATIC VI REFERNCE,选择你要运行的VI,并且指定严格数据类型(鼠标右键)后,红色星号出现.
