X11R6
NAME
  XInstallColormap, XUninstallColormap, XListInstalledColormaps - control
  colormaps

SYNOPSIS
  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 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.
