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