In a multiseat configuration this can be used by the client to help
identify which physical devices the seat represents. Based on
the seat configuration used by the compositor.
In a multi-seat configuration the seat name can be used by clients to
help identify which physical devices the seat represents.
The seat name is a UTF-8 string with no convention defined for its
contents. Each name is unique among all wl_seat globals. The name is
only guaranteed to be unique for the current compositor instance.
The same seat names are used for all clients. Thus, the name can be
shared across processes to refer to a specific wl_seat global.
The name event is sent after binding to the seat global. This event is
only sent once per seat object, and the name does not change over the
lifetime of the wl_seat global.
Compositors may re-use the same seat name if the wl_seat global is
destroyed and re-created later.
