NAME
     XInstallColormap, XUninstallColormap, XListInstalledColor-
     maps - control colormaps

SYNTAX
     XInstallColormap(display, colormap)
           Display *display;
           Colormap colormap;

     XUninstallColormap(display, colormap)
           Display *display;
           Colormap colormap;

     Colormap *XListInstalledColormaps(display, w, num_return)
           Display *display;
           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 color-
               maps.

     w         Specifies the window that determines the screen.

DESCRIPTION
     The XInstallColormap function installs the specified color-
     map 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 color-
     map, 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 XIn-
     stallColormap, 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 color-
     map 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 XUnin-
     stallColormap, 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 speci-
     fied 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.
