XSetWMColormapWindows(3)		  XLIB FUNCTIONS		 XSetWMColormapWindows(3)

NAME
       XSetWMColormapWindows, XGetWMColormapWindows - set or read a window's WM_COLORMAP_WINDOWS
       property

SYNTAX
       Status XSetWMColormapWindows(Display *display, Window w, Window *colormap_windows, int
	      count);

       Status XGetWMColormapWindows(Display *display, Window w, Window **colormap_windows_return,
	      int *count_return);

ARGUMENTS
       display	 Specifies the connection to the X server.

       colormap_windows
		 Specifies the list of windows.

       colormap_windows_return
		 Returns the list of windows.

       count	 Specifies the number of windows in the list.

       count_return
		 Returns the number of windows in the list.

       w	 Specifies the window.

DESCRIPTION
       The XSetWMColormapWindows function replaces the WM_COLORMAP_WINDOWS property on the speci-
       fied window with the list of windows specified by the colormap_windows argument.  It the
       property does not already exist, XSetWMColormapWindows sets the WM_COLORMAP_WINDOWS prop-
       erty on the specified window to the list of windows specified by the colormap_windows
       argument.  The property is stored with a type of WINDOW and a format of 32.  If it cannot
       intern the WM_COLORMAP_WINDOWS atom, XSetWMColormapWindows returns a zero status.  Other-
       wise, it returns a nonzero status.

       XSetWMColormapWindows can generate BadAlloc and BadWindow errors.

       The XGetWMColormapWindows function returns the list of window identifiers stored in the
       WM_COLORMAP_WINDOWS property on the specified window.  These identifiers indicate the col-
       ormaps that the window manager may need to install for this window.  If the property
       exists, is of type WINDOW, is of format 32, and the atom WM_COLORMAP_WINDOWS can be
       interned, XGetWMColormapWindows sets the windows_return argument to a list of window iden-
       tifiers, sets the count_return argument to the number of elements in the list, and returns
       a nonzero status.  Otherwise, it sets neither of the return arguments and returns a zero
       status.	To release the list of window identifiers, use XFree.

       XGetWMColormapWindows can generate a BadWindow error.

PROPERTIES
       WM_COLORMAP_WINDOWS
		 The list of window IDs that may need a different colormap from that of their
		 top-level window.

DIAGNOSTICS
       BadAlloc  The server failed to allocate the requested resource or server memory.

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