我好惭愧!
every 2003-02-27 05:07:58 今天才知道什么所谓的只能意会不能言明?我今天试着译一段c规范,泛泛一读好像明白,可是真的一句一句译的时候我自己什么也不明白了?
希望大家能指出我不对的帮我更正下!谢谢!

As said previously, no variable shared between several modules.
当做先前说, 没有变量在一些模块之间分享。
Rule 16 A local variable to a module is prefixed by the mnemonic of the module, for example:
SVAUD_SourceNumber.
对一个模块的一个局部变量被模块的标志前缀, 举例来说:SVAUD_SourceNumber。
Rule 17 A local variable to a file is not prefixed by the mnemonic of the module, for example:
AudioSourceNumber.
对一个文件的一个区域变量不被模块的标志前缀, 举例来:AudioSourceNumber。
Rule 18 The variable names are in lower case, and each word begins with an upper case, for
example: MyVariable.
变量的名字是小写字母中,而且每个字母开始一个为大写,例子: MyVariable。
Rule 19 The only underscore allowed in a variable name is the one separating the prefix from the
variable name.
唯一的下划线变量命名中允许是一个分开前缀从那变量命名。
Rec. 20 Avoid single letter variables, since they are not meaningful (even if they are used for loop
index).
避免单一文字变量, 既然他们(即使他们作为 loop 索引)命名 ????.
Rule 21 Prefix variables in order to determine their type and their size.
前缀变量为了要决定他们的类型和他们的长短。

2.6 Procedures & Functions
程序与函数
There are three kind sof procedure/function: 有三个类型 sof 程序/函数:
o Those which are local to a file 那些是局部文件
o Those which are private to a module 那些是私有模块
o Those which are exported 那些被输出
Rule 22 An exported procedure/function is prefixed by the module mnemonic, for example
SVAUD_Start.
一个被输出的程序/ 函数被模块标记的前缀,举例来说
SVAUD_Start
Rule 23 A local procedure/function to a module is prefixed by the module mnemonic + i, for example SVAUDi_LevelRead.
对一个模块的一个局部程序/函数被模块标志性的前缀 +i,举例来说 SVAUDi_LevelRead
Rule 24 A local procedure/function to a file is not prefixed.
对一个文件的一个本地程序/函数不用前缀。
Rule 25 The only underscore allowed in a procedure/function name is the one separating the prefix from the function name.
唯一的下划线的在一个程序/函数命名中允许是一个分开来自功能名字的前缀。
Rule 26 Procedure names should reflect what they do. Procedure often acts on objects, and its
name is built as following: ObjectAction. First is the Object and after the Action performed
on the object. For example SVAUD_ConfigSet().
程序名字应该反映他们做的事情。 程序时常对有所反应物件, 和它的
命名依下列各项被建造: ObjectAction。 第一是物件,而且在行动运行之后
在物件上。 举例来说 SVAUD_ConfigSet.()
Rule 27 Function names should reflect what they return. Functions are used in expressions, often in things like if's, so they need to read appropriately. For example:
函数的命名应该反映他们返回的事情。 函数在展示语句中被用, 时常在事物中像如果,因此他们需要适当的读。 举例来说:
if ( SizeCheck( x ) )
is unhelpful since we can not determine whether SizeCheck() returns true on error or nonerror.
Instead:
我们不能决定是否 SizeCheck() 返回真或假。我们应该改成
if ( SizeIsValid( x ) )
makes the point clear and makes a future mistake in routine usage less likely.
指点清楚对以后修改可以减少很多错误。
Rule 28 In order to obtain homogeneous software, please use preferentially the following names
(This list can be extended):
为了使有相同的软件标准,请使用相同的命名。如下列表:
第8页
Init / Terminate 开始/终止
Open / Close 打开/关闭
Connect / Disconnect 连接/断开
Create / Delete 创建/删除
Send / Receive 发送/接受
Wait / Release
Allocate / Free
Get / Set
Add / Remove / Insert
Enter / Exit
Stop / Start / Freeze / Resume
Lock / Unlock
Select / Unselect
Show / Hide
2.7 Defines
Rule 29 A define which is exported (included in an interface file) begins with the module mnemonic. (ex: SVAUD_kChannelNumber)
定义一个输出 (库的接口文件) 由开始模块标记。.
Rule 30 All the defines are prefixed by k, for example kChannelNumber.
所有的那定义都以k为前缀,举例来说 kChannelNumber。
Rule 31 In order to obtain homogeneous software, please use preferentially the following names.
First / Last / Next / Previous
New / Old
On / Off
Min / Max
Source / Destination / Input / Output
Left / Right
Yes / No
为了要获得相同的软件标准的,先请使用下面的命名。
2.8 Macros
Even if the macros are declared using the define key word, they follow a specific naming convention.
即使宏被宣布使用关键子,他们依照一种详细命名规范。
Rule 32 A macro is always prefixed by m, for example mMyMacro.
一个宏总是以m前缀,举例来说 mMyMacro。
Rule 33 Macros follow the same rules as the functions.
宏与函数有相同的规范。
