c - 在 C 中，实现头文件的最低要求是什么？

Question

我有一个这样开头的头文件:

typedef struct PriorityQueueStruct PriorityQueue;

/**
 * Type definition for an Element.
 */
typedef struct ElementStruct
{
    int element;
} Element;

/**
 * Type definition for a priority.
 */
typedef struct PriorityStruct
{
    int priority;
} Priority;

/**
 * Structure for containing the resultant values for a 
 *    call to 'createPriorityQueue'.
 *
 * 'token' is the identifier for the created data structure 
 *     and is to be used in any call to query or modify it.
 * 'resultCode' tells whether the function was successful or not in creating a 
 *     priority queue.  1 for success or an error code describing the failure.
 */
typedef struct InitializationResultStruct
{
        PriorityQueue* pq;
        int resultCode;
} InitializationResult;

/**
 * Structure for containing the resultant values for a 
 *    call to 'peek'.
 *
 * 'peekedValue' is the first-most value from the priority queue
 * 'resultCode' tells whether the function was successful or not in creating a 
 *     priority queue.  1 for success or an error code describing the failure.
 */
typedef struct PeekResultStruct
{
        Element element;
        Priority priority;
        int resultCode;
} PeekResult;

我对如何在我的简单类中实现这个头文件有点迷茫，它是一个优先级队列(称为 TriageQueue)的应用程序。我是否单独保留头文件中的结构？我该如何着手实现功能(感谢提示!)？感谢您的帮助!

Answer 1

C 没有类或方法。它有功能。

是的，假设您必须实现这个特定接口(interface)，当然您需要单独保留声明。

虽然看起来有点不对劲，但注释引用的名称没有出现在声明中(token 和 peekedValue)。
