+.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.
