How do i use Fseek() without having fwrite() replace whatever's there before?
Like I want to seek the pointer to a certain spot, then use fwrite to write something there without replacing what's there already.
And how do I move the pointer down instead of just to the right? Fseek only moves the pointer to the right on the same line of code, I want to be able to move up and down rows, how can i do that?
