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 col-
                 ormaps.

       w         Specifies the window that determines the screen.


DESCRIPTION

       The XInstallColormap function installs the specified col-
       ormap 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 col-
       ormap, 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 Col-
       ormapNotify event on each window that has that colormap.

       XInstallColormap can generate a BadColor error.

       The XUninstallColormap function removes the specified col-
       ormap 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
       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.
