Querying named data streams

In the following example, a file named_stream_file was created with 20 named data streams using the API calls.

The named data streams are not displayed by the ls command. When named data streams are created, they are organized in a hidden directory. For example:

# ls -al named_stream_file

-r-xr-lr-x 1 root other 1024 Aug 12 09:49 named_stream_file

 To query named data streams

• Use the getdents() or readdir_r() system call to query the named_stream_file file for its directory contents, which contains the 20 named stream files:
