fg_setcolornum

Usage

   #include <fg.h>
   int far fg_setcolornum(old,new);

Description


   Change the definition of an FG_COLOR. As in

           fg_setcolornum(FG_WHITE, 3);

   If 3 actually produces green then whenever your program subsequently uses
   FG_WHITE, green will be the actual color output to the screen.

Example 

       .
       .
       .
       if (fg_init() == FG_NULL)
       {
           fputs("Unable to initialize graphics.", stderr);
           return 0;
       }

   /*
           If this board only has 2 colors map the red, green and

           blue colors used throughout the program to black and
           white.
   */
       if (fg.nsimulcolor == 2)
       {
           fg_setcolornum(FG_BLUE, FG_WHITE);
           fg_setcolornum(FG_RED, FG_WHITE);
           fg_setcolornum(FG_GREEN, FG_BLACK);
       }

   /*
           Code originally intended to require red green and blue
       will now have black and white functionality
           (dependent  on the use of the colors.
   */
