c++ - pthread_create with local variable as parameter -

may cause errors when use pthread_create in following way?

void myfunction(){   thread_t mythread;   pthread_create(&mythread,0,myroutine,0); } 

i not sure if usage of local variable mythread can cause errors because ceases exist when myfunction() exits.

could memory of mythread still used in kernel when function exits?

i not need thread id stored in mythread don't want allocate memory , free again.

you can pass pthread_create_detached part of thread attribute when create it. way, dont have worry joining thread later on. this:

 pthread_t;  int status;  pthread_attr_t attr;   status = pthread_attr_init(&attr);  if (status != 0) {      fprintf(stderr, "pthread_attr_init() failed [status: %d]\n", status);      return 0;  }   status = pthread_attr_setdetachstate(&attr, pthread_create_detached);  if (status != 0) {      fprintf(stderr, "pthread_attr_setdetachstate() failed [status: %d]\n", status);      return 0;  }   status = pthread_create(&t, &attr, myroutine, 0);
