SYNOPSIS

cc [ flag ... ] file ... -lXext [ library ... ]
#include <X11/extensions/Xcup.h>
Status XcupGetReservedColormapEntries(Display *display,
int screen, XColor **colors_out, int *ncolors);
ARGUMENTS
display Specifies the connection to the X server.
screen Screen number on the host server.
colors_out
Returns the values reserved by the server.
ncolors Returns the number of items in colors_out.
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 spec‐
ified screen. Use XFree to free colors_out.
To minimize colormap flash, an application which installs its own pri‐
vate colormap should query the special colors by calling XCupGetRe‐
servedColormapEntries, and can then store those entries (in the proper
location) in its private colormap using XCupStoreColors.
