* is to close it, no action need be taken.
* If it is a stream which is unbuffered, no action need be taken.
* If it is a stream which is line buffered, and the last byte written to the stream was a
* <newline> (that is, as if a: putc('\n') was the most recent operation on that stream),
* no action need be taken.
* If it is a stream which is open for writing or appending (but not also open for reading),

* If the stream is open for reading and it is at the end of the file ( feof() is true), no
* action need be taken.
* If the stream is open with a mode that allows reading and the underlying open file
* description refers to a device that is capable of seeking, the application shall
* either perform an fflush(), or the stream shall be closed.
* Otherwise, the result is undefined.
* For the second handle:
* If any previous active handle has been used by a function that explicitly changed the file

* lseek() or fseek() (as appropriate to the type of handle) to an appropriate location.
