You opened a file, sayFILE *fp = fopen("doofus.txt", "r" );
You then tried to seek somewhere - I guessed that fseeki64.c
> stream !=null
How many parameters does fseek() have?
Which one's are
a) pointers …

Which one's are
a) pointers (the message says NULL)
b) could be interpreted as being a stream of some sort.
int fseek(FILE *stream, long offset, int whence);
Mmm, only one thing is a pointer, and it's called stream.
Answer, you passed NULL to fseek.
In other words, you blindly assumed that your file open succeeded and you were wrong.
Improve the error checking in your code.
