问题描述
有关我即将大学C项目，我要求有模块化code为C允许它。基本上，我会.c文件和一些数据结构的相应的.h文件中，就像一个链表，二叉树，哈希表，无论...
For my upcoming university C project, I'm requested to have modular code as C allows it. Basically, I'll have .c file and a corresponding .h file for some data structure, like a linked list, binary tree, hash table, whatever...
使用链表作为一个例子，我有这样的：
Using a linked list as an example, I have this:
typedef struct sLinkedList {
int value;
struct sLinkedList *next;
} List;
但这种力量值为类型 INT 并使用该链表库的用户将被强制直接更改库的源$ C $ C。我想避免这种情况，我想避免需要改变库，使code尽可能模块化。
But this forces value to be of type int and the user using this linked list library would be forced to directly change the source code of the library. I want to avoid that, I want to avoid the need to change the library, to make the code as modular as possible.
我的项目可能需要使用一个链表整数列表，或者一些结构的列表。但我不会重复库文件/ code和相应地改变code。
My project may need to use a linked list for a list of integers, or maybe a list of some structure. But I'm not going to duplicate the library files/code and change the code accordingly.
我该如何解决呢？
推荐答案
不幸的是，解决这个没有简单的方法。最常见的，纯C的方法来这种情况是使用无效* ，和值复制到由你分配为指针内存。这使得使用棘手，不过，很容易出错。
Unfortunately, there is no simple way to solve this. The most common, pure C approach to this type of situation is to use a void*, and to copy the value into memory allocated by you into the pointer. This makes usage tricky, though, and is very error prone.
