结构体指针(关于C语言传值的理解)

//定义一个结构体
struct word_count
{
    int ch_count;
    int word_count;
        int line_count;
};
//定义一个结构体指针
typedef struct word_count *p_count_struct;
//对结构体进行初始化
void init(p_count_struct *count_ent)
{
    (*count_ent) = (struct word_count *)malloc(sizeof(struct word_count));
    (*count_ent)->ch_count = 0;
    (*count_ent)->word_count = 0;
    (*count_ent)->line_count = 0;
//printf("ch_count: %d, word_count: %d, line_count: %d\n", (*count_ent)->ch_count, (*count_ent)->word_count, (*count_ent)->line_count);
}
//main函数调用
int main(int argc, char *argv[])
{
    p_count_struct count_ent;
    init(&count_ent);
    printf("ch_count: %d, word_count: %d, line_count: %d\n", count_ent->ch_count, count_ent->word_count, count_ent->line_count);
}
