当我在函数中打印第一个值后尝试打印f时出现C分段错误

我得到段错误，当我尝试使用printf上*buffer[i]的readWav()功能。并buffer能够正确地传递给main()和我能够在检查值main与datas[i]。我只是复制了printfin main()，必须替换为in datas[i]，*buffer[i]然后编译良好。它打印第一个值readWav()，然后发生SegFault。

如何做到这一点的readWav()-什么是错的*buffer[i])-换句话说，如果datas[i]指的是实际值在main()什么会是这样的readWav()来讲buffer？

更新：main()将传递datas给仍要添加的其他功能。这就是为什么我尝试打印它时readWav()认为它将值传递给其他函数的方式非常相似的原因-如果我写错了，请纠正我？
