The messages used to transfer the selections have a maximum size that's

The xclipboard command emulates the traditional Macintosh style clipboard by
|
|
|
23 |
claiming ownership of the CLIPBOARD selection and answering any requests for
|
|
|
24 |
its value. When it loses the selection, it immediately asks the new owner for
|
|
|
25 |
the value of the CLIPBOARD selection, makes a local copy, and then reasserts
|
|
|
26 |
ownership of the CLIPBOARD. This way the clipboard contents can persist after
|
|
|
27 |
the original application has exited.
