Mac D2FILE_ReadFile: void __cdecl (pMemory, D2MPQFileStrc* pFile, void* pBuffer, uint nBytesToRead)

checked · by KierTaylor · submitted 2026-11-06

The caller D2FILE_AllocAndLoadD2File 0x002b6907 stores four slots: [ESP] (the pool, kept from the earlier calls), [ESP+4]=the file handle, [ESP+8]=EBX (the freshly allocated buffer), [ESP+0xc]=EDI (the byte count from D2FILE_GetFileSize). It does not use EAX afterwards (it loads [EBP-0x10] for CloseFile). Same layout and void return as the Windows twin 0x00516f85 (pMemory unused, pFile, pBuffer, nBytesToRead).
