.SH ARGUMENTS
.IP \fIdisplay\fP 1i
Specifies the connection to the X server.
.IP \fIscreen\fP 1i
Screen number on the host server.
.IP \fIcolors_out\fP 1i
Returns the values reserved by the server.
.IP \fIncolors\fP 1i

.SH DESCRIPTION
.LP
The
.ZN XcupGetReservedColormapEntries
function returns a list of colormap entries (pixels) that are reserved
by the system. This list will, at a minimum, contain entries for the
BlackPixel and WhitePixel of the specified screen. Use
.ZN XFree
to free
.I colors_out.
.LP
To minimize colormap flash, an application which installs its own private
colormap should query the special colors by calling
.ZN XCupGetReservedColormapEntries ,
and can then store those entries (in the
proper location) in its private colormap using
.ZN XCupStoreColors .
