Everything seems to work. 24 * o DPMSGCMD_REQUESTNEWPLAYERID & DPMSGCMD_NEWPLAYERIDREPLY 25 * Barely works. This needs to be completed for sessions to start. 26 * o A small issue will be the fact that DirectX 6.1(ie. DirectPlay4) 27 * introduces a layer of functionality inside the DP objects which 28 * provide guaranteed protocol delivery. This is even if the native 29 * protocol, IPX or modem for instance, doesn't guarantee it. I'm going 30 * to leave this kind of implementation to as close to the end as 31 * possible. However, I will implement an abstraction layer, where 32 * possible, for this functionality. It will do nothing to start, but 33 * will require only the implementation of the guarantee to give 34 * final implementation. 35 * 36 * TODO: 37 * - Implement mutual exclusion on object data for existing functions 38 * - Ensure that all dll stubs are present and the ordinals are correct 39 * - Addition of DirectX 7.0 functionality for direct play 40 * - Implement some WineLib test programs using sdk programs as a skeleton 41 * - Change RegEnumKeyEx enumeration pattern to allow error handling and to 42 * share registry implementation (or at least simplify). 43 * - Add in appropriate RegCloseKey calls for all the opening we're doing... 44 * - Fix all the buffer sizes for registry calls. They're off by one - 45 * but in a safe direction. 46 * - Fix race condition on interface destruction 47 * - Handles need to be correctly reference counted 48 * - Check if we need to deallocate any list objects when destroying 49 * a dplay interface 50 * - RunApplication process spawning needs to have correct synchronization. 51 * - Need to get inter lobby messages working. 52 * - Decipher dplay messages between applications and implement... 53 * - Need to implement lobby session spawning. 54 * - Improve footprint and realtime blocking by setting up a separate data share 55 * between lobby application and client since there can be multiple apps per 56 * client. Also get rid of offset dependency by making data offset independent 57 * somehow. 58 */ 59 #include <stdarg.h> 60 61 #include "winerror.h" 62 #include "windef.h" 63 #include "winbase.h" 64 #include "objbase.h" 65 #include "rpcproxy.h" 66 #include "wine/debug.h" 67 #include "dplayx_global.h" 68 69 WINE_DEFAULT_DEBUG_CHANNEL(dplay); 70 71 static HINSTANCE instance; 72 73 /* This is a globally exported variable at ordinal 6 of DPLAYX.DLL */ 74 DWORD gdwDPlaySPRefCount = 0; /* FIXME: Should it be initialized here? */ 75 76 77 BOOL WINAPI DllMain( HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved ) 78 { 79 80 TRACE( "(%p,%d,%p)\n", hinstDLL, fdwReason, lpvReserved ); 81 82 switch ( fdwReason ) 83 { 84 case DLL_PROCESS_ATTACH: 85 instance = hinstDLL; 86 DisableThreadLibraryCalls(hinstDLL); 87 /* First instance perform construction of global processor data */ 88 return DPLAYX_ConstructData(); 89 90 case DLL_PROCESS_DETACH: 91 /* Last instance performs destruction of global processor data */ 92 return DPLAYX_DestructData(); 93 94 default: 95 break; 96 97 } 98 99 return TRUE; 100 } 101 102 /*********************************************************************** 103 * DllCanUnloadNow (DPLAYX.@) 104 */ 105 HRESULT WINAPI DllCanUnloadNow(void) 106 { 107 HRESULT hr = ( gdwDPlaySPRefCount > 0 ) ?
