ncurses_init_color - Define a terminal color

SYNOPSIS

       int ncurses_init_color (int  $color, int  $r, int  $g, int  $b)

DESCRIPTION

	Defines  or redefines the given color. When this function is called, all occurrences of the given color on the screen, if any, immediately
       change to the new definition.

	Color capabilities must be supported by the terminal and initialized using ncurses_start_color(3) prior to calling this function. In addi-
       tion, the terminal must have color changing capabilities; use ncurses_can_change_color(3) to check for this.

PARAMETERS

	      o $color
		- The identification number of the color to redefine. It may be one of the default color constants.

	      o $r
		- A color value, between 0 and 1000, for the red component.

	      o $g
		- A color value, between 0 and 1000, for the green component.

	      o $b
		- A color value, between 0 and 1000, for the blue component.

RETURN VALUES

	Returns  -1 if the function was successful, and 0 if ncurses or terminal color capabilities have not been initialized or the terminal does
       not have color changing capabilities.

ncurses_color_set - Set active foreground and background colors

SYNOPSIS

       int ncurses_color_set (int  $pair)

DESCRIPTION

	Sets the active foreground and background colors. Any characters written after this function is invoked will have these colors. This func-
       tion requires terminal colors to be supported and initialized using ncurses_start_color(3) beforehand.

	ncurses uses color pairs to specify both foreground and background colors. Use ncurses_init_pair(3) to define a color pair.

PARAMETERS

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

RETURN VALUES

	Returns -1 on success, and 0 on failure.

EXAMPLES

       Example #1

	      Writing a string with a specified color to the screen

	      <?php
	      ncurses_init();

	      // If the terminal supports colors, initialize and set active color
	      if (ncurses_has_colors()) {
		  ncurses_start_color();
		  ncurses_init_pair(1, NCURSES_COLOR_YELLOW, NCURSES_COLOR_BLUE);
		  ncurses_color_set(1);
	      }

	      // Write a string at specified location
	      ncurses_mvaddstr(10, 10, "Hello world! Yellow on blue text!");

	      // Flush output to screen
	      ncurses_refresh();

	      ncurses_end();
	      ?>
