Detailed Description

This API is available only on clients that are eis_client_is_sender(). For those clients the EIS implemententation creates devices and but it is the libei client that sends events to EIS implementation. IOW the EIS implementation acts as the receiver. The primary use-case is input emulation from a client, akin to xdotool.

It is a client bug to call any of these functions for a client created with ei_new_receiver().
