Hello,
why don't you just use (file-select ...) on the STDIN descriptor
(descriptor number 0) directly?
You could also cook up some code using fcntl to switch descriptor 0 into
non-blocking mode, checking for EWOULDBLOCK returns from read calls and
ensuring proper multithreading with the builtin
##sys#thread-block-for-i/o primitive. For an example how that can be
done and neatly wrapped into a custom input port, I suggest you read the
sourcecode of CHICKEN's tcp unit.
cu,
Thomas Chust
