GoogleTest 通过引用初始化

Question

什么原因，为什么GoogleTest对参数计数使用引用？

  testing::InitGoogleTest(&argc, argv);

(我的意思是：据我了解，这是一个输入参数，没有区别是否提供了值或地址）

Answer 1

参见comments。

// Initializes Google Test.  This must be called before calling
// RUN_ALL_TESTS().  In particular, it parses a command line for the
// flags that Google Test recognizes.  Whenever a Google Test flag is
// seen, it is removed from argv, and *argc is decremented.
