- The _X_A_l_l_o_w_D_e_v_i_c_e_E_v_e_n_t_s function releases some queued events
- if the client has caused a device to freeze. It has no
- effect if the specified time is earlier than the last-grab
- time of the most recent active grab for the client and
- device, or if the specified time is later than the current X
- server time.
-
- The following describes the processing that occurs depending
- on what constant you pass to the event_mode argument.
-
- _A_s_y_n_c_T_h_i_s_D_e_v_i_c_e
- If the specified device is frozen by the client,
- event processing for that device continues as
- usual. If the device is frozen multiple times
- by the client on behalf of multiple separate
- grabs, _A_s_y_n_c_T_h_i_s_D_e_v_i_c_e thaws for all.
- _A_s_y_n_c_T_h_i_s_D_e_v_i_c_e has no effect if the specified
- device is not frozen by the client, but the
- device need not be grabbed by the client.
-
- _S_y_n_c_T_h_i_s_D_e_v_i_c_e
- If the specified device is frozen and actively
- grabbed by the client, event processing for that
- device continues normally until the next key or
- button event is reported to the client. At this
- time, the specified device again appears to
- freeze. However, if the reported event causes

- the grab to be released, the specified device
- does not freeze. _S_y_n_c_T_h_i_s_D_e_v_i_c_e has no effect
- if the specified device is not frozen by the
- client or is not grabbed by the client.
-
- _R_e_p_l_a_y_T_h_i_s_D_e_v_i_c_e
- If the specified device is actively grabbed by
- the client and is frozen as the result of an
- event having been sent to the client (either
- from the activation of a GrabDeviceButton or
- from a previous AllowDeviceEvents with mode
- SyncThisDevice, but not from a GrabDevice), the
- grab is released and that event is completely
- reprocessed. This time, however, the request
- ignores any passive grabs at or above (toward
- the root) that the grab-window of the grab just
- released. The request has no effect if the
- specified device is not grabbed by the client or
- if it is not frozen as the result of an event.
-
- _A_s_y_n_c_O_t_h_e_r_D_e_v_i_c_e_s
- If the remaining devices are frozen by the
- client, event processing for them continues as
- usual. If the other devices are frozen multiple
- times by the client on behalf of multiple grabs,
- _A_s_y_n_c_O_t_h_e_r_D_e_v_i_c_e_s "thaws" for all.
- _A_s_y_n_c_O_t_h_e_r_D_e_v_i_c_e_s has no effect if the devices
- are not frozen by the client.
-
- _S_y_n_c_A_l_l If all devices are frozen by the client, event
- processing (for all devices) continues normally
- until the next button or key event is reported
- to the client for a grabbed device, at which
- time all devices again appear to freeze.
- However, if the reported event causes the grab
- to be released, then the devices do not freeze.
- If any device is still grabbed, then a
- subsequent event for it will still cause all
- devices to freeze. _S_y_n_c_A_l_l has no effect unless
- all devices are frozen by the client. If any
- device is frozen twice by the client on behalf
- of two separate grabs, _S_y_n_c_A_l_l thaws for both.
- A subsequent freeze for _S_y_n_c_A_l_l will only freeze
- each device once.
-
- _A_s_y_n_c_A_l_l If all devices are frozen by the client, event
- processing for all devices continues normally.
- If any device is frozen multiple times by the
- client on behalf of multiple separate grabs,
- _A_s_y_n_c_A_l_l thaws for all. _A_s_y_n_c_A_l_l has no effect
- unless all devices are frozen by the client.

- _A_s_y_n_c_T_h_i_s_D_e_v_i_c_e, _S_y_n_c_T_h_i_s_D_e_v_i_c_e, and _R_e_p_l_a_y_T_h_i_s_D_e_v_i_c_e have
- no effect on the processing of events from the remaining
- devices. _A_s_y_n_c_O_t_h_e_r_D_e_v_i_c_e_s has no effect on the processing
- of events from the specified device. When the event_mode is
- _S_y_n_c_A_l_l or _A_s_y_n_c_A_l_l, the device parameter is ignored.
-
- It is possible for several grabs of different devices by the
- same or different clients to be active simultaneously. If a
- device is frozen on behalf of any grab, no event processing
- is performed for the device. It is possible for a single
- device to be frozen because of several grabs. In this case,
- the freeze must be released on behalf of each grab before
- events can again be processed.

- _X_A_l_l_o_w_D_e_v_i_c_e_E_v_e_n_t_s can generate a _B_a_d_D_e_v_i_c_e or _B_a_d_V_a_l_u_e
