Multi-thread Linux programming (1)--common functions

Common functions:

1. Create a thread with the Pthread_create () function. If 0 is returned successfully.

int Pthread_create (pthread_t *thread,                       const pthread_attr_t *attr,                        void * (Start_routine) (void*),                        void * ARG);        

2. Exit Mode:

A. Return returns

B. exit () function, function prototype void exit (int status);

C. pthread_exit function, function prototype void pthread_exit (void * retval);

Note: When you exit using mode B, the entire process will end.

3. Use the Pthread_join () function to connect.

The function function is used to wait for the end of a thread of threads before executing the subsequent content.

Pthread_join (pthread_t thread, void** threadreturn);

Example: pthread_t tid1;

void *join_param;

Pthread_create (&TID1, NULL, PTHREAD_FUNC, NULL); Open a new thread tid1, and run Pthread_func ();

Pthread_join (PID1, &join_param); This connection function was called.

After that, you will wait for the TID1 thread to finish executing before executing the following

printf ("Hello \ n");
