dwindows: template/dw.c comparison

comparison template/dw.c @ 984:57cb9edb8944

Added a template skeleton file for porting DW to other platforms. Also added another error define and used the defines for the return codes in the template. Updated the comments to be more accurate and include return code explanations.
