31 * DirectPlayEnumerateA (DPLAYX.2)
32 *
33 * The pointer to the structure lpContext will be filled with the
34 * appropriate data for each service offered by the OS. These services are
35 * not necessarily available on this particular machine but are defined
36 * as simple service providers under the "Service Providers" registry key.
37 * This structure is then passed to lpEnumCallback for each of the different
38 * services.
39 *
40 * This API is useful only for applications written using DirectX3 or
41 * worse. It is superceeded by IDirectPlay3::EnumConnections which also
42 * gives information on the actual connections.
43 *
44 * defn of a service provider:
45 * A dynamic-link library used by DirectPlay to communicate over a network.
46 * The service provider contains all the network-specific code required
47 * to send and receive messages. Online services and network operators can
48 * supply service providers to use specialized hardware, protocols, communications
49 * media, and network resources.
50 *
51 * TODO: Allocate string buffer space from the heap (length from reg)
52 * Pass real device driver numbers...
53 * Get the GUID properly...
