macro which evaluates stream more than once.

     )putchar(c is equivalent to , putc(c

     Calls to the functions described here can be mixed with
each other and with calls to other output functions from the
stdio library for the same output stream.

an int or EOF on error.

It is not advisable to mix calls to output functions from
the stdio library with low‐level calls to for the file
descriptor associated with the same output stream; the
results will be undefined and very probably not what you
