[問題]請問以下的程式用LINUX泡為何獨不到FORK()和WAIT()啊
#include <pthread.h>
#include <stdio.h>
int value=0;
void *runner(void *param);/* the thread*/
int main(int argc, char *argv[])
{
int pid;
pthread_t tid;
pthread_attr_t attr;
pid=fork();
if (pid==0){/*child process*/
pthread_attr_init(&attr);
pthread_create(&tid,&attr,runner,NULL);
pthread_join(&tid,NULL);
printf("CHILD: value = %d",value);/*LINE c*/
}
else if (pid>0){/*parent process*/
wait(NULL);
printf("PARENT: value = %d" , value);/*LINE P*/
}
}
void *runner(void *param){
value = 5;
pthread_exit(0);
}
麻煩高手回答THX~
