clipboard details

[Thomas Wolff]

2 comments about accessing the Windows clipboard:

* Does the Windows clipboard maintain a timestamp? If so, it would be 
useful to propagate it to /dev/clipboard as its virtual last 
modification time.

* The tools getclip and putclip do not handle non-ASCII character 
properly, while /dev/clipboard does.
   So I'd suggest to replace them with a wrapper:
#! /bin/sh

case "`basename $0`" in
get*)   redir="<";;
put*)   redir=">";;
*)      if [ -t 0 ]
         then    redir="<"
         else    redir=">"
         fi;;
esac

eval cat $redir /dev/clipboard

It doesn't.  The clipboard only supports a sequence number.  It
would be possible to convert that to a virtual modification timestamp,
but it's tricky.  I have an idea how to do it, but I have to test it.

I've just implemented a simple method to store the timestamp in the
clipboard data itself.  Since there's no way to modify stored data, only
one timestamp is stored and then used as modification and access time.
This only works within Cygwin.  If you change the clipboard from outside
Cygwin, the timestamps will be very likely reset because the
Cygwin-specific clipboard data will be deleted, so this is not reliable.
The problem is that the clipboard is window station specific and there's
no way to store window station specific, persistent data somewhere else.
