polling streams

[Noah Roberts]

Hi all
I need a way to poll the input standard stream if there is data to read
from it. Is there any way ( standard )to do this?

There is no standard way. You will need to find a newsgroup particular
to your operating system.

There is no standard way.

That's not right. There is a way: std::cin.rdbuf()->in_avail()

I stand corrected. Here I have been using select all this time...

oh no, seems so basic.
Is there somekind of "workaround", I just need to poll and read a set of
event objects from the cin, but I want the gui to work while reading.
as for now the gui hangs, ( no surprise ) while the read object attempts
to read. could this be done in another way perhaps?
any ideas and help much appreciated

Sort of. You can see if there is any more data buffered using:

is.rdbuf()->in_avail();

If that's not enough, you're going to need platform specific functions
like select or WaitFor*.
