.SH "Detailed Description"
.PP 
data transfer interface 

The wl_data_device_manager is a singleton global object that provides access to inter-client data transfer mechanisms such as copy-and-paste and drag-and-drop\&. These mechanisms are tied to a wl_seat and this interface lets a client get a wl_data_device corresponding to a wl_seat\&.
.PP
Depending on the version bound, the objects created from the bound wl_data_device_manager object will have different requirements for functioning properly\&. See wl_data_source\&.set_actions, wl_data_offer\&.accept and wl_data_offer\&.finish for details\&.
