First off, you answer the wrong question.  The poster wanted to know how much
space was left on the file system, not how big a file was. (Read before you
post)

Using the return from a malloc before you check to see if it is null?
tsk, tsk, tsk.

Calling fprintf without a file pointer????
tsk, tsk, tsk.
