dump command source code
 

Hi,
I am reading the linux dump command source code.
In that dumpino()[dump inode contents on tape] call blksout()
This blksout() is called many times in code.I am not getting use of
this function.Anybody know about this function?

Also in code there are main 4 steps:
1.mapping regular files
2.mapping directories
3.dumping directories
4 dumping regular files

Also i have doubt why dumping directories and dumping files are
separated.If anybody already gone through code pls help me.

Thanks in advance....
