XcupStoreColors(3) X Version 11 XcupStoreColors(3) NAME XcupStoreColors - initialize shareable colormap entries at specific loca- tions SYNOPSIS cc [ flag ... ] file ... -lXext [ library ... ] #include <X11/extensions/Xcup.h> Status XcupStoreColors(Display *display, Colormap colormap, XColor *colors_in_out, int ncolors); ARGUMENTS display Specifies the connection to the X server colormap Specifies the colormap colors_in_out Specifies and returns the values actually used in the colormap ncolors Specifies the number of items in colors_in_out DESCRIPTION The XcupStoreColors function changes the colormap entries of the pixel val- ues in the pixel members of the XColor structures. The colormap entries are allocated as if an AllocColor has been used instead, i.e. the colors are read-only (shareable). XcupStoreColors returns the number of colors that were successfully allocated in the colormap. A Value error is generated if a pixel is not a valid index into the col- ormap. A BadMatch error is generated if the colormap does not belong to a GrayScale, PseudoColor, or DirectColor visual. Applications which allocate many colors in a screen's default colormap, e.g. a color-cube or a gray-ramp, should allocate them with XCupStoreCol- ors. By using XCupStoreColors the colors will be allocated shareable (read-only) and any other application which allocates the same color will share that color cell.
