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