NAME

       XIQueryPointer - get device pointer coordinates.

SYNOPSIS

       #include <X11/extensions/XInput2.h>

       Bool XIQueryPointer( Display *display,
			    int deviceid,
			    Window win,
			    Window *root_return,
			    Window *child_return,
			    double *root_x_return,
			    double *root_y_return,
			    double *win_x_return,
			    double *win_y_return,
			    XIButtonState *buttons_return,
			    XIModifierState *modifiers_return,
			    XIGroupState *group_return);

       buttons_return
	      Returns the current button state.

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

       deviceid
	      Specifies the device to query.

       display
	      Specifies the connection to the X server.

       group_return
	      Returns the current group state.

       modifiers_return
	      Returns the current state of the modifier keys.

       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.

       win
	      Specifies the window.

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

DESCRIPTION

	   The XIQueryPointer function returns the root window the
	   device's pointer is logically on and the pointer coordinates
	   relative to the root window's origin. If XIQueryPointer returns
	   False, the pointer is not on the same screen as the specified
	   window, and XIQueryPointer returns None to child_return and
	   zero to win_x_return and win_y_return. If XIQueryPointer
	   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, XIQueryPointer returns the child that
	   contains the pointer, if any, or else None to child_return.

	   XIQueryPointer returns the current logical state of the buttons
	   buttons_return. The keyboard paired with the master pointer is
	   selected to obtain the data for modifiers_return and
	   group_return.

	   The mask field in buttons_return is dynamically allocated and
	   must be freed by the caller.

	   XIQueryPointer is identical to XQueryPointer but specifies the
	   device explicitly.

	   XIQueryPointer can generate a BadDevice and a BadWindow error.

DIAGNOSTICS

	   BadDevice
		  An invalid device was specified. The device does not
		  exist or is not a pointer device.

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

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.
