dir.read(callback)

• callback <Function>
  • err <Error>
  • dirent <fs.Dirent> | <null>

通过 readdir(3) 异步读取下一个目录条目，作为 <fs.Dirent>。

【Asynchronously read the next directory entry via readdir(3) as an <fs.Dirent>.】

读取完成后，callback 将被调用，并传入一个 <fs.Dirent>，如果没有更多目录条目可读，则传入 null。

【After the read is completed, the callback will be called with an <fs.Dirent>, or null if there are no more directory entries to read.】

此函数返回的目录条目没有特定顺序，它们的顺序由操作系统的底层目录机制提供。在迭代目录时添加或删除的条目可能不会包含在迭代结果中。

【Directory entries returned by this function are in no particular order as provided by the operating system's underlying directory mechanisms. Entries added or removed while iterating over the directory might not be included in the iteration results.】
