**函数注释**:
|
||||
|
||||
- 以 `/**` 开头,以 ` */` 结尾,中间写入函数注释
|
||||
- 第一部分:一个段落介绍函数的作用
|
||||
- 第二部分:参数采用 @param + 参数 + 介绍参数 的方式
|
||||
- 第三部分:返回采用 @return + 返回值 + 介绍返回值 的方式
|
||||
- 以上每个部分之间空一行
|
||||
注释以 `/**` 开头,以 ` */` 结尾,中间写入函数注释,组成元素如下,每个元素描述之间空一行,且首列对齐:
|
||||
|
||||
- @brief + 简述函数作用。在描述中,着重说明该函数的作用,每句话首字母大写,句尾加英文句号。
|
||||
- @note + 函数说明。在上述简述中未能体现到的函数功能或作用的一些点,可以做解释说明,每句话首字母大写,句尾加英文句号。
|
||||
- @see + 相关 API 罗列。若有与当前函数相关度较高的 API,可以进行列举。
|
||||
- @param + 以参数为主语 + be 动词 + 描述,说明参数的意义或来源。
|
||||
- @return + 枚举返回值 + 返回值的意思,若返回值为数据,则直接介绍数据的功能。
|
||||
- @warning + 函数使用注意要点。在函数使用时,描述需要注意的事项,如使用环境、使用方式等。每句话首字母大写,句尾加英文句号。

/**
|
||||
* This function will initialize a semaphore and put it under control of
|
||||
* resource management.
|
||||
* @brief The function will initialize a static event object.
|
||||
*
|
||||
* @param sem the semaphore object
|
||||
* @param name the name of semaphore
|
||||
* @param value the initial value of semaphore
|
||||
* @param flag the flag of semaphore
|
||||
* @note For the static event object, its memory space is allocated by the compiler during compiling,
|
||||
* and shall placed on the read-write data segment or on the uninitialized data segment.
|
||||
* By contrast, the rt_event_create() function will allocate memory space automatically
|
||||
* and initialize the event.
|
||||
*
|
||||
* @return the operation status, RT_EOK on successful
|
||||
* @see rt_event_create()
|
||||
*
|
||||
* @param event is a pointer to the event to initialize. It is assumed that storage for the event
|
||||
* will be allocated in your application.
|
||||
*
|
||||
* @param name is a pointer to the name that given to the event.
|
||||
*
|
||||
* @param value is the initial value for the event.
|
||||
* If want to share resources, you should initialize the value as the number of available resources.
|
||||
* If want to signal the occurrence of an event, you should initialize the value as 0.
|
||||
*
|
||||
* @param flag is the event flag, which determines the queuing way of how multiple threads wait
|
||||
* when the event is not available.
|
||||
* The event flag can be ONE of the following values:
|
||||
*
|
||||
* RT_IPC_FLAG_PRIO The pending threads will queue in order of priority.
|
||||
*
|
||||
* RT_IPC_FLAG_FIFO The pending threads will queue in the first-in-first-out method
|
||||
* (also known as first-come-first-served (FCFS) scheduling strategy).
|
||||
*
|
||||
* NOTE: RT_IPC_FLAG_FIFO is a non-real-time scheduling mode. It is strongly recommended to
|
||||
* use RT_IPC_FLAG_PRIO to ensure the thread is real-time UNLESS your applications concern about
|
||||
* the first-in-first-out principle, and you clearly understand that all threads involved in
|
||||
* this event will become non-real-time threads.
|
||||
*
|
||||
* @return Return the operation status. When the return value is RT_EOK, the initialization is successful.
|
||||
* If the return value is any other values, it represents the initialization failed.
|
||||
*
|
||||
* @warning This function can ONLY be called from threads.

参数:--style=allman
|

格式化代码是指通过脚本自动整理你的代码,并使其符合 RT-Thread 的编码规范。本文提供以下两种自动格式化代码方法,可以自行选择或配合使用。
|
||||
|
||||
### 使用 astyle 格式化
|
||||
|
||||
用 astyle 自动格式化代码,参数如下:
|
||||
|
||||
--style=allman
|
||||
--indent=spaces=4
|
||||
--indent-preproc-block
|

--pad-oper

||||
能满足函数空格、缩进、函数语句等的规范。
|
||||
|
||||
### 使用 formatting 格式化
|
||||
|
||||
使用 [formatting](https://github.com/mysterywolf/formatting) 扫描文件来格式化代码:formatting 可以满足编码规则的基本要求,如:
|
||||
|
||||
- 将源文件编码统一为 UTF-8
|
||||
- 将 TAB 键替换为 4 空格
|
||||
- 将每行末尾多余的空格删除,并统一换行符为 '\n'
