结构文件
{
void * data;
声明一个void类型的指针，这样就可以对任何
数据类型进行类型转换。在卡片游戏中将其视为小丑。你现在不确定所有类型的数据是什么。
};
typedef struct文件文件;
typedef文件* fl;
感谢Jaspreet和SM Ryan为我以前的澄清澄清。
提前致谢

Dear All
What does exactly below code means
struct File
{
void* data;
Declaring a pointer of type void so that it can then be typecast to any
data type. Consider this as a Joker in a game of cards. You are not
sure right now what all type could the data be.
};
typedef struct File File;
typedef File* fl;
And thanks to Jaspreet and SM Ryan for the clarifying my previous
querry.

这声明`struct File''作为结构的类型，
包含一个名为`data'的元素，其类型是指向<的指针br />
`void''。"
typedef struct File File;
这声明`File''作为`struct File''的别名。
typedef文件* fl;
Dear All
What does exactly below code means
struct File
{
void* data;
};
This declares `struct File'' as the type of a struct that
contains one element named `data'' whose type is "pointer to
`void''."
typedef struct File File;
This declares `File'' as an alias for `struct File''.
typedef File* fl;
这将'fl''声明为`File *''的别名，即
作为`struct File *'的别名。

This declares `fl'' as an alias for `File*'', that is,
as an alias for `struct File*''.

Dear All

这声明` struct File''作为结构的类型，
包含一个名为`data'的元素，其类型为指向
`void''的指针。

void *指针不是指向void对象的指针，它是指向任何
对象的指针。它只是你不知道它指向什么类型的物体
！关于这个主题的讨论已在线程中进行：
" void * malloc（size_t num_bytes）;"由Alawna于6月19日开始。（这个
特定的讨论出现在线程的末尾）。此外，
你的意思是什么''指向无效''？

A void * pointer isn''t a pointer to a void object, its a pointer to any
object. Its just that you dont know what type of object its pointing
to! A discussion on this topic was already carried out in the thread:
"void *malloc(size_t num_bytes);" started by Alawna on Jun 19. (This
particular discussion appears towards the end of the thread). Besides,
what do you mean by ''pointer to void''?
