Pthreads

下面介绍一些常用的API

1. 创建一个线程 pthread_create - create a new thread
#include <pthread.h>
int pthread_create(pthread_t *thread, const pthread_attr_t *attr, void *(*start_routine) (void *), void *arg); // 0 on success, or error number

x. 获取线程自身的ID pthread_self - obtain ID of the calling thread
#include <pthread.h>
pthread_t pthread_self(void);
// This function always succeeds, returning the calling thread's ID.
x. 判断两个线程ID是否相同 pthread_equal - compare thread IDs
#include <pthread.h>
int pthread_equal(pthread_t t1, pthread_t t2);
// This function always succeeds. returning nonzero or zero .
x. 获取内核表示的线程ID gettid - get thread identification
#include <sys/types.h>
pid_t gettid(void);
// This call is always succeeds., returning the thread ID of the calling process , not the same thing as a POSIX thread ID

2. 线程结束 pthread_exit - terminate calling thread
#include <pthread.h>
void pthread_exit(void *retval);
// This function always succeeds.
x. 进程结束 exit - cause normal process termination
#include <stdlib.h>
void exit(int status);
// The exit() function does not return.

3. 撤销一个指定的线程 pthread_cancel - send a cancellation request to a thread
#include <pthread.h>
int pthread_cancel(pthread_t thread);
// 0 on success, or error number

4. 向指定的线程发送信号 pthread_kill - send a signal to a thread
#include <signal.h>
int pthread_kill(pthread_t thread, int sig);
// 0 on success, or error number

5. 等待一个指定的线程 pthread_join - join with a terminated thread
#include <pthread.h>
int pthread_join(pthread_t thread, void **retval);
// 0 on success, or error number

6. 设置指定线程的自行回收 pthread_detach - detach a thread
#include <pthread.h>
int pthread_detach(pthread_t thread);
// 0 on success, or error number
// pthread_detach(pthread_self());
