XQueryPointer(3)			  XLIB FUNCTIONS			 XQueryPointer(3)

NAME
       XQueryPointer - get pointer coordinates

SYNTAX
       Bool XQueryPointer(Display *display, Window w, Window *root_return, Window *child_return,
	      int *root_x_return, int *root_y_return, int *win_x_return, int *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 relative 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, XQueryPointer 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.
