虽然 using 重定义的 func_t 是一个模板,但 func_t<int> 定义的 xx_2 并不是一个由类模板实例化后的类,而是 void(*)(int, int) 的别名。 因此,下面这样写: void foo(void (*func_call)(int, int)); void foo(func_t<int> func_call); // error: redefinition 同样是无法实现重载的,func_t<...
using uint_t = int; 1. 2. 3. 通过using 和 typedef 的语法格式可以看到二者的使用没有太大的区别,假设我们定义一个函数指针,using 的优势就能凸显出来了,看一下下面的例子: // 使用typedef定义函数指针 typedef int(*func_ptr)(int, double); // 使用using定义函数指针 using func_ptr1 = int(*)(in...
From version 6.5.0, our OData library starts to provide built-in support for unsigned integer types (includingUInt16,UInt32andUInt64for now) as a protocol extension. Generally a user would have to write very little code to gain a workable model with default implementation of unsigned integers....
