ncurses and blocking?

[Simon Richter]

Hi,

I'm currently writing a program that has a number of input and output
streams operating at various speeds (sockets, local files, NFS files, AFS
files, a Tivoli storage server, ...) that should also get an ncurses
interface. While I realize that ncurses performing blocking I/O will not
be a major problem in most cases, it might be that the controlling tty is
on a slow link (ssh over a modem) while the network around the box running
the program is saturated. Is there a way to tell ncurses to do nonblocking
I/O, probably (though not required) with the option of discarding output
that has not been written to the tty yet but has already been overwritten
on stdscr?
