Subject: Enforcing expected ordering of operations on stdout, stdin, and stderr

All,

I guess my question is more easily asked through an example. If I have code
that makes a call to puts and then a call to getchar, what mechanism
enforces that stdout gets flushed before blocking for stdin? Is there a
such a mechanism? My gut says yes but I haven't been able to pinpoint it.

Thanks,
Max
