changed the return value. Now returns the list of expunged messages
1999-12-16 bertrand <Bertrand.Guiheneuf@aful.org> * camel/camel-folder.c (camel_folder_expunge): (_expunge): * camel/camel-folder-pt-proxy.c (_expunge): changed the return value. Now returns the list of expunged messages * camel/camel-folder.c (_init_with_store): cleaned up. Use the exception system now. (_open): ditto. (camel_folder_open): ditto. (camel_folder_open_async): ditto. (_close): ditto. (camel_folder_close): ditto. (camel_folder_close_async): ditto. * camel/camel-exception.c (camel_exception_set): When no exception is given, do nothing, just return. (camel_exception_set): documented. (camel_exception_new): idem. (camel_exception_free): idem. (camel_exception_xfer): idem. * camel/camel-folder.c: * camel/camel-folder.h: more clean-ups. Removed message list related code. This was braindead design. svn path=/trunk/; revision=1494
