My man page for "open" indicates that the information here on O_CREAT, O_EXCL is incorrect. The information here also ignores the O_TRUNC flag. My understanding is that O_CREAT will not overwrite an existing file. In order to do that you use the O_TRUNC flag. Further, if O_CREAT | O_EXCL is used, the open will fail if the file already exists. Dwkimery 15:37, 23 September 2007 (UTC)
