To write comments to a file, all the comments you wish to add to a file must be set using LFileSettings::SetComment. LFileSettings::SetComment sets each comment individually, but it does not save the comments to the file, it prepares the values for the next save. Once all comments are set, the comments are saved using any function which saves files, such as LFile::SaveFile or LFile::Save when creating a new file. If you wish to change a comment in an existing file, use LFile::WriteComment.
The basic order of function calls for reading comments is as follows:
For an example, refer to LFile::ReadCommentExt.
