No, there is no flush, but there is fflush, and setbuf, setvbuf, _IOFBF,
_IOLBF, _IONBF, and BUFSIZ are all part of the specification; it really
helps if one limits one's authoritative claims to what one actually
knows something about.  While it is true that an ANSI C
stdio implementation can send bytes by bicycle courier, "quality of
implementation" mandates against it.  Byte-at-a-time C (or in fact
POSIX, and thus ADA, given a binding) programs perform well portably, a
fact that no amount of sophistry can cancel.
