linux系统下C语言 利用线程池技术实现CP命令 压缩包包含：源代码+开发说明PPT
线程池头文件：
//任务
struct task
{
void *(*task)(void *arg);
void *arg;
struct task *next;
};
//线程池
typedef struct thread_pool
{
pthread_mutex_t lock;//互斥锁
pthread_cond_t cond;//条件变量
struct task *task_list;//任务队列
pthread_t *tids;//线程id
unsigned waiting_tasks;//等待任务
unsigned active_threads;//
bool shutdown;//停始状态
}thread_pool;
//初始化线程池
bool
init_pool(thread_pool *pool,
unsigned int threads_number);
//新增任务
bool
add_task(thread_pool *pool,
void *(*task)(void *arg),
void *arg);
//新增线程
int
add_thread(thread_pool *pool,
unsigned int additional_threads_number);
//移除线程
int
remove_thread(thread_pool *pool,
unsigned int removing_threads_number);
//销毁线程池
bool destroy_pool(thread_pool *pool);
//处理程序
void *routine(void *arg);
