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