682 * WNetOpenEnumW [MPR.@]
684 * Network enumeration has way too many parameters, so I'm not positive I got
685 * them right. What I've got so far:
687 * - If the scope is RESOURCE_GLOBALNET, and no LPNETRESOURCE is passed,
688 * all the network providers should be enumerated.
690 * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and
691 * and neither the LPNETRESOURCE's lpRemoteName nor the LPNETRESOURCE's
692 * lpProvider is set, all the network providers should be enumerated.
693 * (This means the enumeration is a list of network providers, not that the
694 * enumeration is passed on to the providers.)
696 * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and the
697 * resource matches the "Entire Network" resource (no remote name, no
698 * provider, comment is the "Entire Network" string), a RESOURCE_GLOBALNET
699 * enumeration is done on every network provider.
701 * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and
702 * the LPNETRESOURCE's lpProvider is set, enumeration will be passed through
703 * only to the given network provider.
705 * - If the scope is RESOURCE_GLOBALNET, and LPNETRESOURCE is passed, and
706 * no lpProvider is set, enumeration will be tried on every network provider,
707 * in the order in which they're loaded.
709 * - The LPNETRESOURCE should be disregarded for scopes besides
710 * RESOURCE_GLOBALNET. MSDN states that lpNet must be NULL if dwScope is not
711 * RESOURCE_GLOBALNET, but Windows doesn't return an error if it isn't NULL.
713 * - If the scope is RESOURCE_CONTEXT, MS includes an "Entire Network" net
714 * resource in the enumerated list, as well as any machines in your
715 * workgroup. The machines in your workgroup come from doing a
716 * RESOURCE_CONTEXT enumeration of every Network Provider.
