Wine, WineLib and "Programming Windows 95"

2.18.1. Chapter 20 - caller

Last updated: 2001/4/1

Description

Demonstrates how to use the IMalloc COM interface. This programs has 10 lines which you can either allocate using malloc or IMalloc. To allocate things with IMalloc you must first create an IMalloc object. This program can also query the IUnknown, IMalloc and IMarshal interfaces to discover whether they are supported or not.

Wine tests

• When querying whether an interface is supported the result is displayed in a dialog box. This dialog box contains the 'error' icon whereas in Windows it does not.

Winelib tests

• 'caller.c' contains errors and will not compile as is (whether you use gcc or Visual C++ 5). It passes a GUID instead of a pointer to the GUID in several places. So I provided a patch to make it compile.
• Generates errors:

  compobj.o: In function `DllGetClassObject':
  ~/wine/include/guiddef.h:57: undefined reference to `CLSID_ALLOCATOR'
      

  then

  caller.spec:12: warning: imalloc.dll imported but no symbols used
      

  and

  caller.o: In function `WndProc':
  caller.c:74: undefined reference to `CreateAllocator'

2.18.2. Chapter 20 - callpub

Last updated: 2001/2/28

Description

Same as caller but using the pubmem library.

Wine tests

• Since I did not register the pubmem library this does not work (just as on Windows 95). So I need to register the library and test again.

Winelib tests

• 'callpub.c' contains errors and will not compile as is (whether you use gcc or Visual C++ 5). There are two problems: It defines a variable in the middle of a function (legal in C++ but not in C), and passes a GUID instead of a pointer to the GUID in several places. So I provided a patch to make it compile.
• Generates a warning:

  callpub.spec:12: warning: pubmem.dll imported but no symbols used
      

Tested API

• GDI32
  ExtTextOutA, GetBkColor, GetTextColor, GetTextMetricsA, SetBkColor, SetTextColor, TextOutA

2.18.3. Chapter 20 - imalloc

Last updated: 2001/2/4

Description

This library demonstrates how to implement an OLE/COM object by implementing the IMalloc interface.

Wine tests

• This is a DLL. I cannot test it on its own. See caller.

Winelib tests

• 'imalloc.h' contains an 'extern "C"' directive which is not recognized by the C compiler (whether this is gcc or Visual C++ 5). So I provided a patch to make it compile.
• There's a compilation warning:

  imalloc.cpp: In method `int DAlloc::DidAlloc(void *)':
  imalloc.cpp:128: warning: implicit declaration of function `int memset(...)'
      

Tested API

• KERNEL32
  CloseHandle, DisableThreadLibraryCalls, ExitProcess, FlushFileBuffers, FreeEnvironmentStringsA, FreeEnvironmentStringsW, GetACP, GetCPInfo, GetCommandLineA, GetEnvironmentStrings, GetEnvironmentStringsW, GetFileType, GetLastError, GetModuleFileNameA, GetModuleHandleA, GetOEMCP, GetProcAddress, GetStartupInfoA, GetStdHandle, GetVersion, HeapAlloc, HeapCompact, HeapCreate, HeapDestroy, HeapFree, HeapReAlloc, HeapSize, HeapWalk, LoadLibraryA, SetFilePointer, SetHandleCount, SetStdHandle, WideCharToMultiByte, WriteFile

2.18.4. Chapter 20 - pubmem

Last updated: 2001/2/28

Description

Same as imalloc but with a public server component.

Wine tests

• This is a DLL. I cannot test it on its own. See callpub.

Winelib tests

• 'strlib.h' contains an 'extern "C"' directive which is not recognized by the C compiler (whether this is gcc or Visual C++ 5). So I provided a patch to make it compile.
• There's a compilation warning:

  pubmem.cpp: In method `int DAlloc::DidAlloc(void *)':
  pubmem.cpp:131: warning: implicit declaration of function `int memset(...)'
