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


NAME
       XQueryPointer - get pointer coordinates

SYNTAX
       Bool XQueryPointer(display, w, rootreturn, childreturn,
       rootxreturn, rootyreturn,
                            winxreturn, winyreturn,
       maskreturn)
             Display *display;
             Window w;
             Window *rootreturn, *childreturn;
             int *rootxreturn, *rootyreturn;
             int *winxreturn, *winyreturn;
             unsigned int *maskreturn;

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

       display   Specifies the connection to the X server.

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

       rootreturn
                 Returns the root window that the pointer is in.

       rootxreturn
       rootyreturn
                 Return the pointer coordinates relative to the
                 root window's origin.

       w         Specifies the window.

       winxreturn
       winyreturn
                 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(3X11)       XLIB FUNCTIONS      XQueryPointer(3X11)


       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.
