A stream can be
text or binary. With a binary stream,
there is no transformation between bytes internal and
external to the program. In a text stream, the newline
character '\n' might be transformed to
some other representation externally, e.g. to a carriage return
and a linefeed on some systems.
To open a stream in binary format, include a
b in the mode parameter
of fopen, freopen, fopen_s and freopen_s.
tmpfile always opens a binary stream.
