创建线程时指定线程属性

#include<stdio.h>
#include<pthread.h>

void* start_routine(void *arg)
{
  char *name = (char *) (arg);

  printf("thread %s called.\n", name);
  return NULL;
}

int main()
{

  pthread_attr_t attr;

  if (pthread_attr_init(&attr))
  {
    return 1;
  }

  pthread_create(&pthread, &attr, start_routine, "#1");

  pthread_attr_destroy(&attr);
  return 0;
}

#include<stdio.h>
#include<pthread.h>

  if (pthread_getattr_np(pthread, &attr))
  {
    return NULL;
  }
