ncurses_pair_content - Retrieves foreground and background colors of a color pair

SYNOPSIS

       int ncurses_pair_content (int  $pair, int  &$f, int  &$b)

DESCRIPTION

	Retrieves  the foreground and background colors that constitute the given color pair. Terminal color capabilities must be initialized with
       ncurses_start_color(3) prior to calling this function.

PARAMETERS

	      o $pair
		- The number of the color pair to retrieve information for.

	      o $f
		- A reference to which to return the foreground color of the color pair. The information returned will be a color number referring
		to one of the pre-defined colors or a color defined previously by ncurses_init_color(3) if the terminal supports color changing.

	      o $b
		- A reference to which to return the background color of the color pair. The information returned will be a color number referring
		to one of the pre-defined colors or a color defined previously by ncurses_init_color(3) if the terminal supports color changing.

RETURN VALUES

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