No they can be function macros if you include stdio.h, please read the
standard.

>From C99 (7.1.4/1):
Any function declared in a header may be additionally implemented as a
function-likemacro defined in the header, so if a library function is declared
explicitly when its header is included, one 
of the techniques shown belowcan be used to ensure the declaration is not
affected by 
such a macro.


So you can do:

        p.(fprintf)(&p, "%i", 123);

or
#undef fprintf after including stdio.h.
