24 * FIXME:
25 * - Add WSACancel* and correct handle management. (works rather well for
26 * now without it.)
27 * - Verify & Check all calls for correctness
28 * (currently only WSAGetHostByName*, WSAGetServByPort* calls)
29 * - Check error returns.
30 * - mirc/mirc32 Finger @linux.kernel.org sometimes fails in threaded mode.
31 * (not sure why)
32 * - This implementation did ignore the "NOTE:" section above (since the
33 * whole stuff did not work anyway to other changes).
