            Window w;
            int *num_return;

ARGUMENTS
      colormap  Specifies the colormap.

      display   Specifies the connection to the X server.

      num_return
                Returns the number of currently installed colormaps.

      w         Specifies the window that determines the screen.

DESCRIPTION
      The XInstallColormap function installs the specified colormap for its
      associated screen.  All windows associated with this colormap immediately
      display with true colors.  You associated the windows with this colormap
      when you created them by calling XCreateWindow, XCreateSimpleWindow,
      XChangeWindowAttributes, or XSetWindowColormap.

      If the specified colormap is not already an installed colormap, the X
      server generates a ColormapNotify event on each window that has that
      colormap.  In addition, for every other colormap that is installed as a
      result of a call to XInstallColormap, the X server generates a
      ColormapNotify event on each window that has that colormap.

      XInstallColormap can generate a BadColor error.

      The XUninstallColormap function removes the specified colormap from the
      required list for its screen.  As a result, the specified colormap might
      be uninstalled, and the X server might implicitly install or uninstall
      additional colormaps.  Which colormaps get installed or uninstalled is
      server-dependent except that the required list must remain installed.

      If the specified colormap becomes uninstalled, the X server generates a
      ColormapNotify event on each window that has that colormap.  In addition,
      for every other colormap that is installed or uninstalled as a result of

      a call to XUninstallColormap, the X server generates a ColormapNotify
      event on each window that has that colormap.

      XUninstallColormap can generate a BadColor error.

      The XListInstalledColormaps function returns a list of the currently
      installed colormaps for the screen of the specified window.  The order of
      the colormaps in the list is not significant and is no explicit
      indication of the required list.  When the allocated list is no longer
      needed, free it by using XFree.

      XListInstalledColormaps can generate a BadWindow error.

DIAGNOSTICS
      BadColor  A value for a Colormap argument does not name a defined
                Colormap.

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