Hello,

I need to parse keystrokes that include the escape key or an escape
sequence that may be 3 or 4 chars long.

I can see two options for doing this:

1.  after read() check to see if the char value == 27 and if so then
    read in each subsequent character in the escape sequence if there
    is one.  To do this I need to be able to check for a character
    waiting.

2.  set up a read that does not block. I use the STDIN_FILENO file
    descriptor which is available without use of open().  Therefore I 
    don't have the option of setting the O_NDELAY flag.  Or should I
    open the standard input?

This isn't a new problem so I thought I'd check here to see what the
recommended practice is.

Thanks in advance,
Neal
