@code{fflush} followed by @code{fseek} or @code{fseeko}, applied to an input
|
|
stream, should have the effect of positioning the underlying file descriptor.
|
|
It doesn't do this on some platforms.
|
|
@item
|
|
@code{fflush} on an input stream changes the position of the stream to the
|
|
end of the previous buffer, on some platforms: mingw.

@code{fflush} on an input stream right after @code{ungetc} does not discard
|
|

MacOS X 10.3, FreeBSD 6.0, NetBSD 3.0, OpenBSD 3.8, Cygwin 1.5.25-10.
