I have Stunnel working successfully in a batch file.  I would like to write the error codes in case there is an issue.  How do you do this?

In Windows, I could do something like:

"C:\Program Files\stunnel\stunnel.exe" -start -quiet stunnel.conf

goto %errorlevel%

:0

:: Normal Return – Complete Batch Process

goto :EOF

:1

:: Errors – Log them

Would this work or how do I get the stunnel return codes?
