It's not correct to make a seek here. The file position changes you're 
observing is related to data being read to FILE buffer.

This is also not working in case of small file. invalid_parameter 
handler should only be invoked if data is to big to fit into the buffer.

Probably you did something wrong here. It's allowed to use fread_s and 
fopen (unless there was a broken version of msvcrt90).

This doesn't seem right as well.

It should be easy to add a proper implementation of _fclose_nolock.
