DESCRIPTION¶
The
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
XFree to free
colors_out.
To minimize colormap flash, an application which installs its own private
colormap should query the special colors by calling
XCupGetReservedColormapEntries, and can then store those entries (in
the proper location) in its private colormap using
XCupStoreColors.
