I am currently writing a little applet to modify files in a certain way. However, I am noticing wildly strange behaviour. I have an output file that is fopen'd in "a+" mode. If the file did not exist and was created, the resulting output is total garbage (however, it exhibits …

I've used malloc countless times, but as far as I know, reading and writing to memory that isn't expressly yours (which is in fact done by the malloc function) causes a segfault. If I wanted to make my own dynamic allocation functions my computer would probably just laugh at me …
