- _d_i_s_p_l_a_y Specifies the connection to the X server.
-
- _d_e_v_i_c_e Specifies the device from which the events are
- to be sent.
-
- _d_e_s_t_i_n_a_t_i_o_n Specifies the window the event is to be sent
- to. You can pass window id, _P_o_i_n_t_e_r_W_i_n_d_o_w, or

- event_list.
-
- _e_v_e_n_t___l_i_s_t Specifies the list of event selections to be
- used.

- The _X_S_e_n_d_E_x_t_e_n_s_i_o_n_E_v_e_n_t request identifies the des-
- tination window, determines which clients should
- receive the specified events, and ignores any
- active grabs. This request requires you to pass an
- event class list. For a discussion of the valid
- event class names, see _X_O_p_e_n_D_e_v_i_c_e_(_3_X_1_1_). This
- request uses the w argument to identify the desti-
- nation window as follows:
-
- +o If w is _P_o_i_n_t_e_r_W_i_n_d_o_w , the destination window is the
- window that contains the pointer.
-
- +o If w is _I_n_p_u_t_F_o_c_u_s and if the focus window contains
- the pointer, the destination window is the window
- that contains the pointer; otherwise, the destination

- window is the focus window.
-
- To determine which clients should receive the specified
- events, _X_S_e_n_d_E_x_t_e_n_s_i_o_n_E_v_e_n_t uses the propagate argument as
- follows:
-
- +o If event_list is the empty set, the event is sent to
- the client that created the destination window. If
- that client no longer exists, no event is sent.
-
- +o If propagate is _F_a_l_s_e, the event is sent to every
- client selecting on destination any of the event
- types specified by the event_list array.
-
- +o If propagate is _T_r_u_e and no clients have selected on
- destination any of the events specified by the
- event_list array, the destination is replaced with
- the closest ancestor of destination for which some
- client has selected a type specified by the event-
- list array and for which no intervening window has
- that type in its do-not-propagate-mask. If no such
- window exists or if the window is an ancestor of the
- focus window and _I_n_p_u_t_F_o_c_u_s was originally specified
- as the destination, the event is not sent to any
- clients. Otherwise, the event is reported to every
- client selecting on the final destination any of the
- events specified in the event_list array.
-
- The event in the _X_E_v_e_n_t structure must be one of the
- events defined by the input extension (or a _B_a_d_V_a_l_u_e error
- results) so that the X server can correctly byte-swap the
- contents as necessary. The contents of the event are oth-
- erwise unaltered and unchecked by the X server except to
- force send_event to _T_r_u_e in the forwarded event and to set
- the serial number in the event correctly.
-
- _X_S_e_n_d_E_x_t_e_n_s_i_o_n_E_v_e_n_t returns zero if the conversion to wire
- protocol format failed and returns nonzero otherwise.
- _X_S_e_n_d_E_x_t_e_n_s_i_o_n_E_v_e_n_t can generate _B_a_d_C_l_a_s_s, _B_a_d_D_e_v_i_c_e, _B_a_d_-
- _V_a_l_u_e, and _B_a_d_W_i_n_d_o_w errors.

- _B_a_d_D_e_v_i_c_e An invalid device was specified. The speci-
- fied device does not exist or has not been
- opened by this client via _X_O_p_e_n_I_n_p_u_t_D_e_v_i_c_e.
- This error may also occur if the specified
- device is the X keyboard or X pointer device.
-
- _B_a_d_V_a_l_u_e Some numeric value falls outside the range of
- values accepted by the request. Unless a spe-
- cific range is specified for an argument, the
- full range defined by the argument's type is
- accepted. Any argument defined as a set of
- alternatives can generate this error.
