pub fn init_pair(
pair_index: i16,
foreground_color: i16,
background_color: i16,
) -> i32Expand description
Change the definition of a color pair. Does not do anything if colors are disabled.
Changes the definition of a color-pair.
It takes three arguments: the number of the color-pair to be redefined, and the new values of
the foreground and background colors. The pair number must be between 0 and COLOR_PAIRS - 1,
inclusive. The foreground and background must be between 0 and COLORS() - 1, inclusive. If the
color pair was previously initialized, the screen is refreshed, and all occurrences of that
color-pair are changed to the new definition.
