什么是用C最常见的命名约定? [英] What are the most common naming conventions in C?
本文介绍了什么是用C最常见的命名约定?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
什么是命名约定常用的C使用?我知道至少有二:
- 的GNU / Linux / K&安培; R与lower_case_functions
- ?名称 ?与UpperCaseFoo功能
我只是在这里谈论℃。我们的大多数项目都是我们用C小型嵌入式系统中。
下面是一个我使用我的下一个项目的规划:
ç命名约定
结构体的首字母大写
结构成员LOWER_CASE或小写枚举ETitleCase
枚举成员ALL_CAPS或小写公共职能pfx_TitleCase(PFX =两个或三个字母的模块preFIX)
私有函数的首字母大写
琐碎的变量I,X,N,F等...
局部变量LOWER_CASE或小写
全局变量g_lowerCase或g_lower_case(由G_ preFIX搜索)
解决方案
这里最重要的事情是一致性。这就是说,我按照GTK +编码惯例,可归纳如下:
- 在瓶盖的所有宏和常量:
MAX_BUFFER_SIZE
,TRACKING_ID_ preFIX
- 结构体的名称和类型定义的首字母大写:
的GtkWidget
,TrackingOrder
- ,关于结构操作功能:经典的C风格:
gtk_widget_show()
,tracking_order_process()
- 指针:这里没有什么花哨的:
的GtkWidget *富
,TrackingOrder *栏
。 - 全局变量:只是不使用全局变量。他们是邪恶的。
- 函数是有的,但
不应该被直接调用,或有
晦涩的用途,或什么:一个或多个
强调开头:_refrobnicate_data_tables()
,_destroy_cache()
。
What are the naming conventions commonly use in C? I know there are at least two:
- GNU / linux / K&R with lower_case_functions
- ? name ? with UpperCaseFoo functions
I am talking about C only here. Most of our projects are small embedded systems in which we use C.
Here is the one I am planning on using for my next project:
C Naming Convention
Struct TitleCase
Struct Members lower_case or lowerCase
Enum ETitleCase
Enum Members ALL_CAPS or lowerCase
Public functions pfx_TitleCase (pfx = two or three letter module prefix)
Private functions TitleCase
Trivial variables i,x,n,f etc...
Local variables lower_case or lowerCase
Global variables g_lowerCase or g_lower_case (searchable by g_ prefix)
解决方案
The most important thing here is consistency. That said, I follow the GTK+ coding convention, which can be summarized as follows:
- All macros and constants in caps:
MAX_BUFFER_SIZE
,TRACKING_ID_PREFIX
. - Struct names and typedef's in camelcase:
GtkWidget
,TrackingOrder
. - Functions that operate on structs: classic C style:
gtk_widget_show()
,tracking_order_process()
. - Pointers: nothing fancy here:
GtkWidget *foo
,TrackingOrder *bar
. - Global variables: just don't use global variables. They are evil.
- Functions that are there, but
shouldn't be called directly, or have
obscure uses, or whatever: one or more
underscores at the beginning:
_refrobnicate_data_tables()
,_destroy_cache()
.
