NAME _set_color - Inline version of set_color(). Allegro game programming library.
SYNOPSIS #include <allegro.h> void _set_color(int index, const RGB *p);
DESCRIPTION This is an inline version of set_color(), intended for use in the vertical retrace simula‚Äź tor callback function (retrace_proc, which is now deprecated). If you really must use _set_color from retrace_proc, note that it should only be used under DOS, in VGA mode 13h and mode-X. Some SVGA chipsets aren't VGA compatible (set_color() and set_palette() will use VESA calls on these cards, but _set_color() doesn't know about that).
