Right. It's not there by design.

This function is not actually part of C++ standard iostreams.

>From 2.95.3, it looks like this function did:

    int ipfx(int need = 0) {
	if (!good()) { set(ios::failbit); return 0; }
	else {
	  _IO_flockfile(_strbuf);
	  if (_tie && (need == 0 || rdbuf()->in_avail() < need)) _tie->flush();
	  if (!need && (flags() & ios::skipws)) return _skip_ws();
	  else return 1;
	}
    }
    int ipfx0() { // Optimized version of ipfx(0).
	if (!good()) { set(ios::failbit); return 0; }
	else {
	  _IO_flockfile(_strbuf);
	  if (_tie) _tie->flush();
	  if (flags() & ios::skipws) return _skip_ws();
	  else return 1;
	}
    }

You'll have to use something equivalent, but standards conforming,
when you port.
