DESCRIPTION
The XSetWMColormapWindows function replaces the WM_COL-
ORMAP_WINDOWS property on the specified window with the
list of windows specified by the colormap_windows argu-
ment. It the property does not already exist, XSetWMCol-
ormapWindows sets the WM_COLORMAP_WINDOWS property on the
specified window to the list of windows specified by the
colormap_windows argument. The property is stored with a
type of WINDOW and a format of 32. If it cannot intern
the WM_COLORMAP_WINDOWS atom, XSetWMColormapWindows
returns a zero status. Otherwise, it returns a nonzero
status.
XSetWMColormapWindows can generate BadAlloc and BadWindow
errors.
The XGetWMColormapWindows function returns the list of
window identifiers stored in the WM_COLORMAP_WINDOWS prop-
erty on the specified window. These identifiers indicate

the colormaps that the window manager may need to install
for this window. If the property exists, is of type WIN-
DOW, is of format 32, and the atom WM_COLORMAP_WINDOWS can
be interned, XGetWMColormapWindows sets the windows_return
argument to a list of window identifiers, sets the
count_return argument to the number of elements in the
list, and returns a nonzero status. Otherwise, it sets
neither of the return arguments and returns a zero status.
To release the list of window identifiers, use XFree.
XGetWMColormapWindows can generate a BadWindow error.
