XSetWMColormapWindows(3X11)					  XLIB FUNCTIONS				       XSetWMColormapWindows(3X11)

NAME
XSetWMColormapWindows, XGetWMColormapWindows - set or read a window's WM_COLORMAP_WINDOWS property SYNTAX
Status XSetWMColormapWindows(Display *display, Window w, Window *colormap_windows, int count); Status XGetWMColormapWindows(Display *display, Window w, Window **colormap_windows_return, int *count_return); ARGUMENTS
display Specifies the connection to the X server. colormap_windows Specifies the list of windows. colormap_windows_return Returns the list of windows. count Specifies the number of windows in the list. count_return Returns the number of windows in the list. w Specifies the window. DESCRIPTION
The XSetWMColormapWindows function replaces the WM_COLORMAP_WINDOWS property on the specified window with the list of windows specified by the colormap_windows argument. It the property does not already exist, XSetWMColormapWindows 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 property on the specified win- dow. These identifiers indicate the colormaps that the window manager may need to install for this window. If the property exists, is of type WINDOW, 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. PROPERTIES
WM_COLORMAP_WINDOWS The list of window IDs that may need a different colormap from that of their top-level window. DIAGNOSTICS
BadAlloc The server failed to allocate the requested resource or server memory. BadWindow A value for a Window argument does not name a defined Window. SEE ALSO

       The function replaces the WM_COLORMAP_WINDOWS property on the specified window with the list of windows specified by the colormap_windows
       argument.  It the property does not already exist, 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

       The function returns the list of window identifiers stored in the WM_COLORMAP_WINDOWS property 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 WINDOW, is of for-
       mat 32, and the atom WM_COLORMAP_WINDOWS can be interned, sets the windows_return argument to a list of window identifiers, sets the
       count_return argument to the number of elements in list, and returns a non-zero status.	Otherwise, it sets neither of the return arguments
       and returns a zero status.  To release the list of window identifiers, use

       can generate a error.
