pthread创建和退出

#include 
#include 

#define NUM_THREAD 5

void *print_hello(void *threadid)
{
        long tid;
        tid = (long)threadid;
        printf("Hello world! thread#%ld\n", tid);
        pthread_exit(NULL);
}

int main()
{
        pthread_t threads[NUM_THREAD];
        int rc; 
        long i;
        for(i =0; i 
 
 
 
 
 
输出：
 
 
In main: create thread 0
In main: create thread 1
In main: create thread 2
In main: create thread 3
In main: create thread 4
Hello world! thread#4
Hello world! thread#3
Hello world! thread#2
Hello world! thread#1
Hello world! thread#0
