LINUX线程分离

linux 环境中可以通过pthread_detach( phtread_id) 函数对线程进行分离

1.可以在子线程中加入代码 pthread_detach(pthread_self())

2.或者在父线程调用pthread_detach(thread_id)

使用简单的

#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
void *thread_function(void *arg)
{
// pthread_detach(pthread_self());在子线程中使用
char* cmd = (char*)arg;
printf("cmd: %s \n",cmd);
system(cmd);
while(1);
}

void cmd (char * cmd1,char *cmd2,char * cmd3)
{
pthread_t thread1,thread2,thread3;
/*char * cmd1 = "ls";
char * cmd2 = "ls";
char * cmd3 = "ls";
*/
pthread_create(&thread1, NULL, thread_function, (void *)cmd1);  //
pthread_create(&thread2, NULL, thread_function, (void *)cmd2);
pthread_create(&thread3, NULL, thread_function, (void *)cmd3);

pthread_detach(thread1);  // 2 在主线程中分离线程
pthread_detach(thread2);
pthread_detach(thread3);

}

int main()
{
cmd("ls","ls","ls");

sleep(2);
printf("hahao end end ");
}
