In a very subtle and * obscure way. DLLs can reference each other recursively etc. * - If you want to enhance, speed up or clean up something in here, think * twice WHY it is implemented in that strange way. There is usually a reason. * Though sometimes it might just be lazyness ;) * - In PE_MapImage, right before fixup_imports() all external and internal * state MUST be correct since this function can be called with the SAME image * AGAIN. (Thats recursion for you.) That means MODREF.module and * NE_MODULE.module32. * - No, you (usually) cannot use Linux mmap() to mmap() the images directly. * * The problem is, that there is not direct 1:1 mapping from a diskimage and * a memoryimage. The headers at the start are mapped linear, but the sections * are not. For x86 the sections are 512 byte aligned in file and 4096 byte * aligned in memory. Linux likes them 4096 byte aligned in memory (due to * x86 pagesize, this cannot be fixed without a rather large kernel rewrite) * and 'blocksize' file-aligned (offsets). Since we have 512/1024/2048 (CDROM) * and other byte blocksizes, we can't do this. However, this could be less * difficult to support... (See mm/filemap.c). * - All those function map things into a new addresspace. From the wrong * process and the wrong thread. So calling other API functions will mess * things up badly sometimes. */ #include #include #include #include #include #include #include #include #include "windows.h" #include "winbase.h" #include "callback.h" #include "file.h" #include "heap.h" #include "neexe.h" #include "peexe.h" #include "process.h" #include "thread.h" #include "pe_image.h" #include "module.h" #include "global.h" #include "task.h" #include "snoop.h" #include "debug.h" static void PE_InitDLL(WINE_MODREF *wm, DWORD type, LPVOID lpReserved);
