...doesn''t work right. I need some help. I don''t understand what, exactly, I''m supposed to pass to ReadDirectoryChangesW() for the 2nd argument, nor how to read the data back out. There''s also a WCHAR issue that needs to be worked out with regards to the FileName FILE_NOTIFY_INFORMATION struct member. Please see the changenotify_init() function in changenotify.c. HELP! Regards, Dan

...cated, but people seem to still be using win32-changenotify, so I thought I''d see if I could make it pure Ruby. Also, I thought it would be a good opportunity to test passing a custom Win32::Event object. I''m mostly done I think, but I''m having trouble unraveling the FILE_NOTIFY_INFORMATION struct buffer. Please check out the latest lib/win32/changenotify.rb from CVS and take a look at both the custom wait method and the get_file_action private method. The notification is clearly getting picked up, but I''m just not unraveling the struct properly. Here''s a little...

...ction: " + cns.action } cn.wait That means altering changenotify.c to use ReadDirectoryChangesW() instead of FindFirstChangeNotification(). Our Ruby ChangeNotifyStruct would contain two members, "action" and "file_name" that would be the Action and FileName members of the FILE_NOTIFY_INFORMATION structure. I''ve tinkered around with this but I''m having a couple issues. I can open a directory and call ReadDirectoryChangesW() successfully, but I can''t figure out how to read back out of the buffer (nor am I exactly sure what to pass as a buffer in the first place)....

Hi all, I decided to check the responsiveness of the pure Ruby vs C extension versions of win32-changenotify. I setup this little file generator program: a = [] 10.times{ |n| a << Thread.new{ File.open("File_#{n}", ''w''){ |fh| fh.puts "test #{n}" } } } a.each{ |t| t.join } The pure Ruby version did not do so well. In some cases it
