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 win-
		 dow.

DESCRIPTION
       The XQueryPointer function returns the root window the pointer is logi-
       cally on and the pointer coordinates relative to the root window's ori-
       gin.  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 XQuery-
       Pointer 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 bit-
       wise 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.
