Umm, not well-documented, but a little poking revealed this (won't work in Warp 3 or Warp 4 prior to FP13): APIRET APIENTRY DosSysCtl(ULONG func, ULONG p); ULONG SavedDosError = 1; DosSysCtl((ULONG)27, (ULONG)&SavedDosError); DosError(0L); //FERR_DISABLEHARDERROR ... DosError(SavedDosError); Hope this helps.
