for my map format I want to keep it simple, yet cryptic so stupid people can''t edit the file. I won''t be using any kind of compression or anything. my two questions are. 1: can I load a text file and save it as a binary file? 2: once I load a binary file, how do I actually read the data? (like sscanf() for text files) thanks, Joe JoeMont001@aol.com www.polarisoft.n3.net

Yep. No reason why you shouldn''t be able to. Just load the data into an array of chars then save out that array in binary mode.

thanks



I personally like to use fopen, fread, fwrite etc. They''re pretty easy to use.

Yes, but if you do that it will probably be exactly the same as the original text file. Text and binary are really no different. To say a file is text is to say that it consists of basically just the ''printable'' characters. A text file is logically assumed to be a sequence of ''lines'' seperated by carriage-returns/line-feed pairs (on the PC; usually just line-feeds on *nix systems).

Possibly come up with a ''binary'' method of manipulating the file; or converting from text to a more ''binary'' format.

2: once I load a binary file, how do I actually read the data? (like sscanf() for text files)

Umm.. once you ''load a binary file'', then you have already ''read the data''.... But to read a binary file, try using the fopen(), fread(), fclose() sequence of functions.
