openssh unix dev - Dec 2012 - Warning/Diagnostic/Error Codes

I'd consider this a bug in documentation as in the lack of documentation. 
I've looked all over the openssh.org Web site and done a number of Google
searches and can not find anything.  I'd like to know what error codes, if
any, mean.  For example, if I do an 'scp', and it fails, will it return
a different error code depending on what the error was?  Do I get one code if I
can't connect to the remote system?  A different one if the file or
directory I reference doesn't exist?  All the manual says is '0' on
success and '>0' for any errors.  I'd like something more
specific, if it exists.  I found a couple of references to some error codes on a
couple of Web sites, but one sounded like they could be only for their locally
modified version.  The other didn't look 'official' either.

I suggest that you use one of the several existing SSH client
libraries and implement your own client, in order to work directly
with the SSH protocol. These things become trivial then.
