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 immedi-
       ately display with true colors.	You associated the windows with this colormap when you created them by calling XCreateWindow, XCreateSim-
       pleWindow, 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 Col-
       ormapNotify 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 unin-
       stalled 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.
