+ X/Open defines no error conditions. This implementation
+ will return <STRONG>ERR</STRONG> on attempts to use color values outside
+ the range 0 to COLORS-1 (except for the default colors ex-
+ tension), or use color pairs outside the range 0 to COL-
+ OR_PAIR-1. Color values used in <STRONG>init_color</STRONG> must be in the
+ range 0 to 1000. An error is returned from all functions
+ if the terminal has not been initialized. An error is re-
+ turned from secondary functions such as <STRONG>init_pair</STRONG> if
+ <STRONG>start_color</STRONG> was not called.
+
+ <STRONG>init_color</STRONG>
+ returns an error if the terminal does not sup-
+ port this feature, e.g., if the <EM>initial-</EM>
+ <EM>ize</EM><STRONG>_</STRONG><EM>color</EM> capability is absent from the termi-
+ nal description.
+
+ <STRONG>start_color</STRONG>
+ returns an error If the color table cannot be
+ allocated.
