It's not a good idea to read the whole file. Imagine what can happen if your file is 100MB. I'd rather make a dynamic buffer (with defined max size and procedures what to do when it's reached) and read the amount of data needed at the moment.
Well, how about not doing it?
I had to do a read and substitute file parser.
I didn't bother with that, keep it simple.
Open the file and copy it to another.
then re-open the copy again for rw and using, ftell(), fseek(), fgetc and fputc(), you can navigate in the
copied file, change it and let the standard libraries worry about the buffering and such.
