如何在结构之外记录结构数据成员

Question

当我用 Doxygen 记录函数时，我可以这样做：

/*!
 * @brief does something
 * @param a first parameter
 *
 * Longer description
 */
void foo(int a) { /* */ }

但是我有没有办法以这种方式记录结构成员：

/*!
 * @brief a struct
 * @??? a first struct member
 * @??? b second struct member
 *
 * Longer description
 */
struct a 
{
    int a,
    int b,
};

原因是，如果可能的话，我想避免使用内联注释来记录我的结构成员。

Answer 1

/*!
 * @struct str_a
 * @brief my a struct
 * @details Longer description
 *
 * @var str_a::a
 *   @brief first struct member
 *   @details detailed first struct member
 * @var str_a::b
 *   @brief brf second struct member
 *   @details detailed second struct member
 *
 */
struct str_a
{
    int a;
    int b;
};
