VBoxSDL.cpp@ 44970

Last change on this file since 44970 was 44970, checked in by vboxsync, 12 years ago
Main/VirtualBoxClient: add method to perform VM error checking which simplifies client code com/ErrorInfo: small bugfix (the object where the error information originated was always lost), added a way to inject whole error object structures which needed the bugfix Frontends/VBoxSDL: sample code how to use the new method
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
