Why won't fclose work?

[wtf]

I've narrowed the segmentation fault down to the line:

     fclose(outputfile);

What am I doing wrong? code executes fine until then, but nothing afterwards. What are some possible causes?

should I do fclose(&outputfile) instead? or something like that?

edit: sorry never mind.... it had never opened successfully.... lol

You could have knackered you program earlier. How was outputfile initialised.
