1 文件头部信息

/*! \file ClassA.h*  \brief     文件说明 定义了类fatherA*  \details   This class is used to demonstrate a number of section commands.*  \author    John Doe*  \author    Jan Doe*  \version   4.1a*  \date      2023-2199*  \pre       First initialize the system.*  \bug       Not all memory is freed when deleting an object of this class.*  \warning   Improper use can crash your application*  \copyright GNU Public License.*/

2 class

/*! \class Test classA.h "inc/classA.h"\brief fatherA类Some details about the Test class.*/

2 变量

/*! \var int errno\brief Contains the last error code.\warning Not thread safe!
*/

3 函数

例子1

/*! \fn int read(int fd,char *buf,size_t count)\brief Read bytes from a file descriptor.\param fd The descriptor to read from.\param buf The buffer to read into.\param count The number of bytes to read.
*/

例子2

/*! \fn void Overload_Test::drawRect(int x,int y,int w,int h)* This command draws a rectangle with a left upper corner at ( \a x , \a y ),* width \a w and height \a h. */

例子3

class Fn_Test
{public:const char *member(char,int) throw(std::out_of_range);
};const char *Fn_Test::member(char c,int n) throw(std::out_of_range) {}/*! \class Fn_Test* \brief Fn_Test class.** Details about Fn_Test.*//*! \fn const char *Fn_Test::member(char c,int n) *  \brief A member function.*  \param c a character.*  \param n an integer.*  \exception std::out_of_range parameter is out of range.*  \return a character pointer.*/

struct CoordStruct
{/*! The x coordinate */float x;/*! The y coordinate */float y;
};

6 枚举

class Enum_Test
{public:enum TEnum { Val1, Val2 };/*! Another enum, with inline docs */enum AnotherEnum { V1, /*!< value 1 */V2  /*!< value 2 */};
};/*! \class Enum_Test* The class description.*//*! \enum Enum_Test::TEnum* A description of the enum type.*//*! \var Enum_Test::TEnum Enum_Test::Val1* The description of the first enum value.*/

7 宏

/*! \brief Computes the absolute value of its argument \a x.\param x input value.\returns absolute value of \a x.
*/
#define ABS(x) (((x)>0)?(x):-(x))/*!\def MAX(x,y)Computes the maximum of \a x and \a y.
*/
#define MAX(x,y) ((x)>(y)?(x):(y))
