想问各位常指针引用做函数参数的问题
by 黄铎彦 21 Feb '24

21 Feb '24

在内存表的事务模块（\\src\gausskernel\storage\mot\core\system\transaction\txn.h）中，可以看到常指针引用做函数参数，如下图所示注意到红框框住的几个参数都是类似于 Type* const& 的形式。我的想法是，这里其实可以直接使用 Type* const 的形式，因为指针为值类型，作参数粒度小，并且函数中修改指针指向的地址，不会影响到主调函数，和原来意义一致。

在内存表的事务模块（\\src\gausskernel\storage\mot\core\system\transaction\txn.h）中，可以看到常指针引用做函数参数，如下图所示注意到红框框住的几个参数都是类似于 Type* const& 的形式。我做了一个实验： #include <typeinfo> #include <stdio.h> typedef int Type, * TypePtr; typedef Type* const& Foo; typedef const TypePtr& Bar; int main() { printf("%d\n", typeid(Foo) == typeid(Bar)); return 0; } 运行之后，程序输出了1。说明参数对应的就是实验程序中的Bar类型。我觉得，指针变量本来就是值，并不是类类型，再加一个&会导致出现间接寻址，加大开销。
