ncurses_color_set — Set active foreground and background colors

说明

ncurses_color_set ( int $pair ) : int

Sets the active foreground and background colors. Any characters written after this function is invoked will have these colors. This function requires terminal colors to be supported and initialized using ncurses_start_color() beforehand.

ncurses uses color pairs to specify both foreground and background colors. Use ncurses_init_pair() to define a color pair.

参数

The color pair from which to get the foreground and background colors to set as the active colors.

返回值
