/prog/ - Reading files backwards

how do you read files backwards in C?

read the whole file into a string, then call string.reverse (which you will define), then it's just a mattSegmentation Fault

for(;;)

{ fread(buffa, 1, 1, files);

  fseek(files, -2, SEEK_CUR); }

How did I formulate questions in a way that produces usable answers?

I actually did that the first time I had to read in a file backwards :( I read in the files in chunks and pushed those onto a stack. Then as I popped the chunks off again, I copied them into a buffer rear-end first. It worked, but when I remembered fseek I wanted to kill myself.

I wanted to kill myself.

YOU MIGHT AS WELL DO IT.

finish the quote!
the first time I had to read in a file backwards
I'd been programming for 2 years at that point (I was taught VB in high school :( ) and had worked with files, but I'd never had to read them backwards.(That's what tac is for)
