You can pass AsyncThisDevice, SyncThisDevice, ReplayThisDevice, AsyncOtherDevices, SyncAll, or AsyncAll\&. .fi .sp .nf time Specifies the time\&. You can pass either a timestamp or CurrentTime\&. .fi .SH "DESCRIPTION" .sp The XAllowDeviceEvents 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\&. .sp The following describes the processing that occurs depending on what constant you pass to the event_mode argument\&. .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} AsyncThisDevice \- 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, AsyncThisDevice thaws for all\&. AsyncThisDevice has no effect if the specified device is not frozen by the client, but the device need not be grabbed by the client\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} SyncThisDevice \- 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\&. SyncThisDevice has no effect if the specified device is not frozen by the client or is not grabbed by the client\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} ReplayThisDevice \- 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\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} AsyncOtherDevices \- 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, AsyncOtherDevices "thaws" for all\&. AsyncOtherDevices has no effect if the devices are not frozen by the client\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} SyncAll \- 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\&. SyncAll 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, SyncAll thaws for both\&. A subsequent freeze for SyncAll will only freeze each device once\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} AsyncAll \- 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, AsyncAll thaws for all\&. AsyncAll has no effect unless all devices are frozen by the client\&. .RE .sp AsyncThisDevice, SyncThisDevice, and ReplayThisDevice have no effect on the processing of events from the remaining devices\&. AsyncOtherDevices has no effect on the processing of events from the specified device\&. When the event_mode is SyncAll or AsyncAll, the device parameter is ignored\&. .sp 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\&. .sp XAllowDeviceEvents can generate a BadDevice or BadValue error\&. .SH "DIAGNOSTICS" .sp .if n \{\ .RS 4 .\} .nf BadDevice An invalid device was specified\&. The specified device does not exist or has not been opened by this client via XOpenInputDevice\&. This error may also occur if the specified device is the X keyboard or X pointer device\&. .fi .if n \{\ .RE .\} .sp .if n \{\ .RS 4 .\} .nf BadValue An invalid mode was specified on the request\&. .fi .if n \{\ .RE .\} .SH "SEE ALSO" .sp .if n \{\ .RS 4 .\} .nf XGrabDevice(libmansuffix) .fi .if n \{\ .RE .\}
