Subject: printf.help


Hi there,

I have a printf problem (or more to the point a problem that occurs when
printing text to the console) which seems to have popped up out of the
blue.  It looks to me like a buffering issue.

I have some code :-

	printf("Enter S for simulate or R for real > ");
	key = getkey();
	switch(key)
	{
		....
	}


It only outputs the printf string after I press one of the appropriate keys.
I looked at the FAQ and it suggested cprintf, cputs or using the fflush(stdout)
to force the buffer's contents to the screen.  These methods haven't work.

Am I misdiagnosing the problem or doing something wrong.  I can't recall 
having this problem with printf before.  I even tried putting a \n at the end
of the string hoping it would flush the buffer.

Hope someone can help with this hopefully simple problem.  Does V2 handle
buffered output any differently to V1.  Should I be using cprintf instead of
printf as a rule.  What about portability...

Regards
Brendan Simon
