自动打印struct [英] print struct automaticly

问题描述

我必须打印几个大的结构来打印屏幕。

我想知道它们是否是一个自动执行此工具的工具


struct A


{

int i;

char * s;

}

A a;


它会打印出来的内容：

i = 0

s =" somestring

等;

Thanx。

Kat。

No.在ISO C中没有这样的东西，如果你想要wr你自己也会有一个很好的任务，你自己也有一个很好的任务。对于初学者来说，

在ISO C中无法让你的程序得到一个随机结构成员的名字（而不是

值） - 除了记住它从

开始，这反而削弱了工具的普遍性。

一个足够狡猾的工具 - 或者C / C
中足够透明的标记 - 可以从结构声明中生成打印代码，

是吗？一般吗？


当然，有关/

结构中的项目应该打印的各种问题。一般来说，我会把

struct-printer函数写成

属于struct [1]的函数集群的一部分;由于较小结构的大结构增长，我不会面对哦/ frelling / tedium，我有

来写一个打印功能117元素结构/现在/！ （另外

无论如何我都不会写一个扁平的117元素结构。）


[1] EG打印一个，初始化一个，malloc一个， free（一个指针）一个，

测试其中两个是否相等/相似，从一个

简单的字符串描述中构造一个，用一杯可可发送一个到床上

和一本好书。

您可能希望查看一些特定于平台的内容（如STABS和

DWARF调试格式）以查看它们是否合适，但是这不是

标准C语言的一部分。


对于一般用途，Chris Dollin的建议似乎是最合适的。

I have to print several large structs to print the screen.
I was wondering if thers a tool to do so automaticly

struct A

{
int i;
char * s;
}

A a;

it will print it''s contents :
i=0
s="somestring
etc;
Thanx.
Kat.

No. There is no such thing in ISO C, and if you want to write one
yourself you''ll have a nice task on your hands, too. For starters, there
is no way in ISO C to let your program get at the names (rather than the
values) of a random struct member - except for remembering it from the
start, which rather puts a dent in the generality of the tool.

A sufficiently cunning tool -- or sufficiently transparent markup in
the C code -- can generate the printing code from the struct declaration,
yes? General enough?

Of course there are all sorts of issues about /how/ the items in the
struct(s) should be printed. Generally speaking, I''d write the
struct-printer function as part of the cluster of functions that
belong with the struct [1]; since large structs from smaller structs
grow, I wouldn''t be faced with the "oh /frelling/ tedium, I have
to write a print function for a 117-element struct /now/!". (Also
I wouldn''t write a flat 117-element struct anyway.)

[1] EG print one, initialise one, malloc one, free (a pointer to) one,
test two of them for equality/similarity, construct one from a
simple string description, send one to bed with a cup of cocoa
and a good book.

You may like to look at some platform-specifics (like the STABS and
DWARF debugging formats) to see if they are appropriate, but that''s not
part of the standard C language.

For general purposes, Chris Dollin''s suggestion seems most appropriate.
