ncurses_init_pair - Define a color pair

SYNOPSIS

       int ncurses_init_pair (int  $pair, int  $fg, int  $bg)

DESCRIPTION

	Defines  or  redefines	the given color pair to have the given foreground and background colors. If the color pair was previously initial-
       ized, the screen is refreshed and all occurrences of it are changed to reflect the new definition.

	Color capabilities must be initialized using ncurses_start_color(3) before calling this function. The first color pair (color pair  0)	is
       assumed to be white on black by default, but can be changed using ncurses_assume_default_colors(3).

PARAMETERS

	      o $pair
		- The number of the color pair to define.

	      o $fg
		-  The	foreground  color  for the color pair. May be one of the pre-defined colors or one defined by ncurses_init_color(3) if the
		terminal has color changing capabilities.

	      o $bg
		- The background color for the color pair. May be one of the pre-defined colors or one defined	by  ncurses_init_color(3)  if  the
		terminal has color changing capabilities.

RETURN VALUES

	Returns -1 if the function was successful, and 0 if ncurses or color support were not initialized.

NOTES

	Note  that color changing capabilities are not required for defining color pairs of pre-existing colors, but only for changing definitions
       (red, green, and blue components) of colors themselves per ncurses_init_color(3).

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();
	      ?>
