如何将一个结构体定义为多个名称? [英] How a struct being typedef-ed to multiple names?

问题描述

我最近开始研究结构体和指针，但是对于 struct 的设计，我还没有完全理解.我了解 struct 的声明，即 typedef struct Alias 及其内容，但我不了解 Get_noAllyp 和 *no_getOf 在语句的末尾.这些是什么?我也找不到好的来源.

I've recently started to study about structs and pointers but there is something I didn't fully understand about the design of a struct. I understand the declaration of the struct i.e typedef struct Alias and its content but I don't understand Get_noAllyp and *no_getOf at the end of the statement. What are they? I couldn't really find a good source either.

typedef struct  Alias {
    char    *s_a_name;
    char    **s_aliases;
    short   *s_dumr;
    int     s_get_sum;
}Get_noAllyp, *no_getOf; /*Here, I don't understand this one. 
                        Where did these two variables come from?
                        And one of them is a pointer.*/

推荐答案

它定义了多个 typedef，即同一事物的多个名称"，而第二个是指向它的指针.

It defines multiple typedefs, i.e multilple "names" for the same thing, while the second is a pointer to it.

第一个 Get_noAllyp 是结构的名称，而 no_getOf 表示指向它的指针.

The first one Get_noAllyp is the name given for the struct, while no_getOf represents a pointer to it.

即，编写no_getOf 与在函数签名或变量声明中编写Get_noAllyp * 完全相同.

I.e, writing no_getOf is completely the same as writing Get_noAllyp * in function signatures or variable declarations.
