i work with text-files that i opened with fopen. i can get and restor the curent psoition by using fgetpos and fsetpos. but is it also possible to just move the pointer one element backward or forwar by simply incrementing the handle or something similar? always storing and setiting the position isn't too efficient i think. is it also possible to jump to a known position (for example i know that i just have to start with the 1000 st char) without just looping and reading char after char till 100 is reached?
