The problem is you have to tell VioGetMode the size of the return buffer.
This code is part of PDCurses for DOS and OS/2 (a rewrite and update to 
PCCurses 1.4 for DOS that includes color, pads and most System V R3.2 
functions) and works:


VIOMODEINFO modeInfo;

modeInfo.cb = sizeof(modeInfo);
VioGetMode(&modeInfo, 0);
