编了一个小小的程序，竟然不能编译, 提示：

lovelypengpeng

test.c 内容如下:
#include <stdio.h>
#include <sys/time.h>

int main(int argc, char *argv[])
{
  struct time_val now;

  gettimeofday(&now, NULL);
  printf("Status report type %s \n", ctime(&(now.tv_sec)));
  
  return 0;
}

gcc test.c -o test,提示:
storage size of 'now' isn't know.

felix

struct time_val now;  错了！
改为
struct timeval now;
即可！
