C语言写一个ring buff

er(环形缓冲区)的代码怎么写？

以下是一个简单的 C 语言环形缓冲区的示例代码：

typedef struct {
int head;
int tail;
int size;
int *data;
} RingBuffer;

void RingBuffer_Init(RingBuffer *buffer, int size) {
buffer->head = 0;
buffer->tail = 0;
buffer->size = size;
buffer->data = (int*) malloc(sizeof(int) * size);
}

void RingBuffer_Enqueue(RingBuffer *buffer, int value) {
int next_tail = (buffer->tail + 1) % buffer->size;
if (next_tail != buffer->head) {
buffer->data[buffer->tail] = value;
buffer->tail = next_tail;
}
}

int RingBuffer_Dequeue(RingBuffer *buffer) {
if (buffer->tail != buffer->head) {
int value = buffer->data[buffer->head];
buffer->head = (buffer->head + 1) % buffer->size;
return value;
} else {
return -1;
}
}

void RingBuffer_Free(RingBuffer *buffer) {
free(buffer->data);
}

在上述代码中，RingBuffer_Init 函数用于初始化环形缓冲区，RingBuffer_Enqueue 函数用于将元素放入缓冲区中，RingBuffer_Dequeue 函数用于从缓冲区中取出元素。RingBuffer_Free 函数则用于释放环形缓冲区所占用的内存空间。
