XInstallColormap(3X11)	  XLIB FUNCTIONS   XInstallColormap(3X11)


NAME
       XInstallColormap, XUninstallColormap, XListInstalledCol
       ormaps - 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 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
       remain installed.

XInstallColormap(3X11)	  XLIB FUNCTIONS   XInstallColormap(3X11)


       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 col
       ormap that is installed or uninstalled as a result of a
       call to XUninstallColormap, the X server generates a Col_
       ormapNotify 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.
