Differences from Win32
The following properties of RTTarget-32's DLL support differ from Win32's implementation:
- LoadLibrary always supports DLLs included with the DLL command. It can load DLLs as files only if they are converted to DLMs and if the file system RTFiles-32 is used.
- GetProcAddress finds exported entrypoints only in modules which have their .edata section mapped on the target using Locate Section or Locate NTSection.
- GetModuleHandle will return the handle of the module containing Rtt32.lib for module names Kernel32.dll, User32.dll, Advapi32.dll, Oleaut32.dll, and Rtt32dll.dll.
- At program termination, the DllEntryPoint functions are not called for event DLL_PROCESS_DETACH. If this is required by an application, it should call FreeLibrary or RTDLLThreadEvent(NULL, DLL_PROCESS_DETACH) instead.
- The data segment of a DLL is not reloaded when a DLL is initialized more than once.
