File I/O problems
Well, I''ve come to the point where I have to ask for help. I''m writing a 2d isometric tile game in c++, directx 9. Basically for my map I have a linked list of struct GTILE''s. I have very little experience with file i/o and I can''t seem to get the maps to load and save right. The code compiles fine, and I see the map file being created in my directory, but when I load the file it doesn''t load any of the map information, either that or its not saving the map information. Here are my save and load functions, please let me know if you see something wrong.
