Hi Takashi,

I noticed that cygwin clipboard is not compatible

If I run 'echo AAAAAAAA > /dev/clipboard' in 32bit cygwin,
and run 'cat /dev/clipboard' in 64bit cygwin, this result in
cat: /dev/clipboard: Bad address
This is because the structure
typedef struct
{
timestruc_t timestamp;
size_t len;
char data[1];
} cygcb_t;
defined in fhandler_clipboard.cc has different size.
Is this the known issue?
I doubt anybody has ever tried what you did.
I have and it failed; I just didn't find it important enough to report
it here... Thanks for the plan to fix it.
I have been testing getclip and putclip between 32- and 64-bit
environments, but neglected to test Cygwin-internal clipboard format
that prepends cygcb_t to the user-supplied data. So getclip and
putclip will need fixing as well.
I will submit a Cygwin patch to fix /dev/clipboard usage and a similar
patch to cygutils for the utilities.
I appreciate your help in uncovering and investigating bugs in
clipboard support.
Thanks & Regards,
