-Specifies the cursor that is to be displayed during the grab or

-.IP \fIdisplay\fP 1i
-Specifies the connection to the X server.
-.IP \fIevent_mask\fP 1i
-Specifies which pointer events are reported to the client.
-The mask is the bitwise inclusive OR of the valid pointer event mask bits.
-.IP \fIgrab_window\fP 1i
-Specifies the grab window.
-.IP \fIkeyboard_mode\fP 1i
-Specifies further processing of keyboard events.
-You can pass
-.ZN GrabModeSync
-or
-.ZN GrabModeAsync .
-.IP \fIowner_events\fP 1i
-Specifies a Boolean value that indicates whether the pointer
-events are to be reported as usual or reported with respect to the grab window
-if selected by the event mask.
-.IP \fIpointer_mode\fP 1i
-Specifies further processing of pointer events.
-You can pass
-.ZN GrabModeSync
-or
-.ZN GrabModeAsync .
-.IP \fItime\fP 1i
-Specifies the time.
-You can pass either a timestamp or
-.ZN CurrentTime .
-.SH DESCRIPTION
-The
-.ZN XGrabPointer
-function actively grabs control of the pointer and returns
-.ZN GrabSuccess
-if the grab was successful.
-Further pointer events are reported only to the grabbing client.
-.ZN XGrabPointer
-overrides any active pointer grab by this client.
-If owner_events is
-.ZN False ,
-all generated pointer events
-are reported with respect to grab_window and are reported only if
-selected by event_mask.
-If owner_events is
-.ZN True
-and if a generated
-pointer event would normally be reported to this client,
-it is reported as usual.
-Otherwise, the event is reported with respect to the
-grab_window and is reported only if selected by event_mask.
-For either value of owner_events, unreported events are discarded.
-.LP
-If the pointer_mode is
-.ZN GrabModeAsync ,
-pointer event processing continues as usual.
-If the pointer is currently frozen by this client,
-the processing of events for the pointer is resumed.
-If the pointer_mode is
-.ZN GrabModeSync ,
-the state of the pointer, as seen by
-client applications,
-appears to freeze, and the X server generates no further pointer events
-until the grabbing client calls
-.ZN XAllowEvents
-or until the pointer grab is released.
-Actual pointer changes are not lost while the pointer is frozen;
-they are simply queued in the server for later processing.
-.LP
-If the keyboard_mode is
-.ZN GrabModeAsync ,
-keyboard event processing is unaffected by activation of the grab.
-If the keyboard_mode is
-.ZN GrabModeSync ,
-the state of the keyboard, as seen by
-client applications,
-appears to freeze, and the X server generates no further keyboard events
-until the grabbing client calls
-.ZN XAllowEvents
-or until the pointer grab is released.
-Actual keyboard changes are not lost while the pointer is frozen;
-they are simply queued in the server for later processing.
-.LP
-If a cursor is specified, it is displayed regardless of what
-window the pointer is in.
-If
-.ZN None
-is specified,
-the normal cursor for that window is displayed
-when the pointer is in grab_window or one of its subwindows;
-otherwise, the cursor for grab_window is displayed.
-.LP
-If a confine_to window is specified,
-the pointer is restricted to stay contained in that window.
-The confine_to window need have no relationship to the grab_window.
-If the pointer is not initially in the confine_to window,
-it is warped automatically to the closest edge
-just before the grab activates and enter/leave events are generated as usual.
-If the confine_to window is subsequently reconfigured,
-the pointer is warped automatically, as necessary,
-to keep it contained in the window.
-.LP
-The time argument allows you to avoid certain circumstances that come up
-if applications take a long time to respond or if there are long network
-delays.
-Consider a situation where you have two applications, both
-of which normally grab the pointer when clicked on.
-If both applications specify the timestamp from the event,
-the second application may wake up faster and successfully grab the pointer
-before the first application.
-The first application then will get an indication that the other application
-grabbed the pointer before its request was processed.
-.LP
-.ZN XGrabPointer
-generates
-.ZN EnterNotify
-and
-.ZN LeaveNotify
-events.
-.LP
-Either if grab_window or confine_to window is not viewable
-or if the confine_to window lies completely outside the boundaries of the root
-window,
-.ZN XGrabPointer
-fails and returns
-.ZN GrabNotViewable .
-If the pointer is actively grabbed by some other client,
-it fails and returns
-.ZN AlreadyGrabbed .
-If the pointer is frozen by an active grab of another client,
-it fails and returns
-.ZN GrabFrozen .
-If the specified time is earlier than the last-pointer-grab time or later
-than the current X server time, it fails and returns
-.ZN GrabInvalidTime .
-Otherwise, the last-pointer-grab time is set to the specified time
-.Pn ( CurrentTime
-is replaced by the current X server time).
-.LP
-.ZN XGrabPointer
-can generate
-.ZN BadCursor ,
-.ZN BadValue ,
-and
-.ZN BadWindow
-errors.
-.LP
-The
-.ZN XUngrabPointer
-function releases the pointer and any queued events
-if this client has actively grabbed the pointer from
-.ZN XGrabPointer ,
-.ZN XGrabButton ,
-or from a normal button press.
-.ZN XUngrabPointer
-does not release the pointer if the specified
-time is earlier than the last-pointer-grab time or is later than the
-current X server time.
-It also generates
-.ZN EnterNotify
-and
-.ZN LeaveNotify
-events.
-The X server performs an
-.ZN UngrabPointer
-request automatically if the event window or confine_to window
-for an active pointer grab becomes not viewable
-or if window reconfiguration causes the confine_to window to lie completely
-outside the boundaries of the root window.
-.LP
-The
-.ZN XChangeActivePointerGrab
-function changes the specified dynamic parameters if the pointer is actively
-grabbed by the client and if the specified time is no earlier than the
-last-pointer-grab time and no later than the current X server time.
-This function has no effect on the passive parameters of a
-.ZN XGrabButton .
-The interpretation of event_mask and cursor is the same as described in
-.ZN XGrabPointer .
-.LP
-.ZN XChangeActivePointerGrab
-can generate a
-.ZN BadCursor
-and
-.ZN BadValue
-error.
-.SH DIAGNOSTICS
-.TP 1i
-.ZN BadCursor
-A value for a Cursor argument does not name a defined Cursor.
-.TP 1i
-.ZN BadValue
-Some numeric value falls outside the range of values accepted by the request.
-Unless a specific 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.
-.TP 1i
-.ZN BadWindow
-A value for a Window argument does not name a defined Window.

+The
+.ZN XUngrabPointer
+function releases the pointer and any queued events
+if this client has actively grabbed the pointer from
+.ZN XGrabPointer ,
+.ZN XGrabButton ,
+or from a normal button press.
+.ZN XUngrabPointer
+does not release the pointer if the specified
+time is earlier than the last-pointer-grab time or is later than the
+current X server time.
+It also generates
+.ZN EnterNotify
+and
+.ZN LeaveNotify
+events.
+The X server performs an
+.ZN UngrabPointer
+request automatically if the event window or confine_to window
+for an active pointer grab becomes not viewable
+or if window reconfiguration causes the confine_to window to lie completely
+outside the boundaries of the root window.
+.LP
+The
+.ZN XChangeActivePointerGrab
+function changes the specified dynamic parameters if the pointer is actively
+grabbed by the client and if the specified time is no earlier than the
+last-pointer-grab time and no later than the current X server time.
+This function has no effect on the passive parameters of a
+.ZN XGrabButton .
+The interpretation of event_mask and cursor is the same as described in
+.ZN XGrabPointer .
