Flush to stdio?

[Dleaner]

I was using writef("escape string" ~ "Display string") to try to 
simulate a console, but noticed that the writes are only flushed 
when a newline is present.

Is there a 'flush' function that works with stdio?
'flush()' seems unkown to the compiler, and 'fflush()' seems to 
be for files, not for writing to the screen.
