<description summary="control data devices">
|
||||
This protocol allows a privileged client to control data devices. In
|
||||
particular, the client will be able to manage the current selection and take
|
||||
the role of a clipboard manager.
|
||||
|
||||
Warning! The protocol described in this file is experimental and
|
||||
backward incompatible changes may be made. Backward compatible changes
|
||||
may be added together with the corresponding interface version bump.
|
||||
Backward incompatible changes are done by bumping the version number in
|
||||
the protocol and interface names and resetting the interface version.
|
||||
Once the protocol is to be declared stable, the 'z' prefix and the
|
||||
version number in the protocol and interface names are removed and the
|
||||
interface version number is reset.

To transfer the offered data, the client issues this request and

indicates the MIME type it wants to receive. The transfer happens

through the passed file descriptor (typically created with the pipe

system call). The source client writes the data in the MIME type

representation requested and then closes the file descriptor.

The receiving client reads from the read end of the pipe until EOF and
|
||||
then closes its end, at which point the transfer is complete.

This request may happen multiple times for different MIME types.
