<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Wrong: OpenHistory takes care of most of the fclose's.
(1) Change OpenHistory to set *f = NULL after fclose and here do an if(f){fclose(f);}
or
(2) Have OpenHistory fclose(*f) if count==0.
Logically, I'd prefer the first. But the second will reduce the amount of extra if's you'll have to write. Better go with the last one.</pre>

Thou shall not fclose a FILE pointer twice. And in all cases of errors, OpenHistory already closes it. The only missing fclose is when there is no error, but count is 0.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">i dont think so.
there was no { } before, so it means
class->total_files = 0;
was called just once, after the for loop.
It doesnt make sense to call that initialisation many times, no?
I added braces though.</pre>

Why? Because when I was looking for what happens if we break early from there and re-enter the function later: I saw free's, but I didn't see any nullification to prevent the free's from being done a second time. Turns out, it was there, but was leaning against the getcwd-check.
It has nothing to do with braces, just with logical ordering. I wanted:
BLOCK_THAT_FREES_STUFF_AND_SETS_IT_TO_ZERO
ENTER
BLOCK_THAT_DOES_GETCWD
and not
BLOCK_THAT_FREES_STUFF
ENTER
BLOCK_THAT_SETS_SOMETHING_TO_ZERO_AND_DOES_GETCWD</pre>
