Prototypes translations

i'm translating svgalib header file (vga.h) under pascal to make it simply available by using vga.gpi. i have some troubles in translating some things, and i ask you for help... these are things i can't translate (they are part of a struct/record) {FIXME void *extensions;} {FIXME char *linear_aperture;} {FIXME void (*set_aperture_page) (int page);} {FIXME unsigned char *colors)} thanks in advance -- Nicola Girardi aka nikke <girardi@keycomm.it>
