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