XQueryPointer(3X11)	XLIB FUNCTIONS	    XQueryPointer(3X11)

NAME
       XQueryPointer - get pointer coordinates

SYNTAX
       Bool XQueryPointer(display, w, root_return, child_return,
       root_x_return, root_y_return,
			    win_x_return, win_y_return,
       mask_return)
	     Display *display;
	     Window w;
	     Window *root_return, *child_return;
	     int *root_x_return, *root_y_return;
	     int *win_x_return, *win_y_return;
	     unsigned int *mask_return;

ARGUMENTS
       child_return
		 Returns the child window that the pointer is
		 located in, if any.

       display	Specifies the connection to the X server.

       mask_return
		 Returns the current state of the modifier keys
		 and pointer buttons.

       root_return
		 Returns the root window that the pointer is in.

       root_x_return
       root_y_return
		 Return the pointer coordinates relative to the
		 root window's origin.

       w	 Specifies the window.

       win_x_return
       win_y_return
		 Return the pointer coordinates relative to the
		 specified window.

DESCRIPTION
       The XQueryPointer function returns the root window the
       pointer is logically on and the pointer coordinates rela-
       tive to the root window's origin.  If XQueryPointer
       returns False, the pointer is not on the same screen as
       the specified window, and XQueryPointer returns None to
       child_return and zero to win_x_return and win_y_return.
       If XQueryPointer returns True, the pointer coordinates
       returned to win_x_return and win_y_return are relative to
       the origin of the specified window.  In this case, XQuery-
       Pointer returns the child that contains the pointer, if
       any, or else None to child_return.

       XQueryPointer returns the current logical state of the
       keyboard buttons and the modifier keys in mask_return.  It
       sets mask_return to the bitwise inclusive OR of one or
       more of the button or modifier key bitmasks to match the
       current state of the mouse buttons and the modifier keys.

       XQueryPointer can generate a BadWindow error.

DIAGNOSTICS
       BadWindow A value for a Window argument does not name a
		 defined Window.
