DESCRIPTION

The XStoreColors function changes the color map entries of the pixel values specified in the pixel members of the XColor structures. .PN XStoreColors can generate BadAccess, BadColor, and BadValue errors.

The XStoreColor function changes the color map entry of the pixel value specified in the pixel member of the XColor structure. .PN XStoreColor can generate BadColor and BadValue errors.

The XStoreNamedColor function looks up the named color with respect to the screen associated with cmap and stores the result in cmap. .PN XStoreNamedColor can generate BadAccess, BadColor, BadName, and BadValue errors.

DIAGNOSTICS

BadAccess A client attempted to free a color map entry that it did not already allocate.

BadAccess A client attempted to store into a read-only color map entry.

BadColor A value for a Colormap argument does not name a defined Colormap.

BadName A font or color of the specified name does not exist.

BadValue Some numeric value falls outside the range of values accepted by the request. Unless a specific range is specified for an argument, the full range defined by the argument’s type is accepted. Any argument defined as a set of alternatives can generate this error.
