What is the preferred way to determine if a key has been pressed
on the keyboard when running UNIX Sys V?  I know that some UN*X
versions have ioctl()s for checking the input queue size (in
some cases the ioctl() is undocumented), but I don't see anything
like that in Sys V.

Please mail responses back to me.  I rarely reach the net.

	Thanks in advance!
