struct 定义和初始化语法疑问

这是使用FUSE文件系统中的代码,对于

问题1:为什么有 “=” ?

struct fuse_operations bb_oper = { ... }

问题2:下面的这个语法规则是初始化吗?第一次见到感觉很奇怪

.getattr = bb_getattr

附录:
结构体

struct fuse_operations bb_oper = {
  .getattr = bb_getattr,
  .readlink = bb_readlink,
  .getdir = NULL,
  .mknod = bb_mknod,
  .mkdir = bb_mkdir,
  .unlink = bb_unlink,
  .rmdir = bb_rmdir,
  .symlink = bb_symlink,
  .rename = bb_rename,
......
};
