windows c++获取文件信息——_stat函数的使用

struct _stat64 state;

    int res = _stat64("420.yuv", &state); //file size more than 2G
    if (res < 0)
    {
        switch (errno)
        {
        case ENOENT:
            printf("File %s not found.\n", "420.yuv");
            break;
        case EINVAL:
            printf("Invalid parameter to _stat.\n");
            break;
        default:
            /* Should never be reached. */
            printf("Unexpected error in _stat.\n");
        }

        fprintf(stderr, "Faile to stat %s/n", res);
        return -1;
    }
