Specifies the connection to the X server.
.IP \fIscreen\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 .
