_set_color (3alleg4)

#include <allegro.h>

void _set_color(int index, const RGB *p);

This is an inline version of set_color(), intended for use in the vertical retrace simulator 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).
