This issue is for tracking the status of converting the project to C in order to get things more binary exact.

General issue

• storm.h isn't loaded in a way that allows the compiler to recognize the function names.
• diabloui.h isn't loaded in a way that allows the compiler to recognize the function names.
• static float *_cpp_init_value = INFINITY; this was probably put here by the compiler because of crtical sections or similar and should be safe to remove for now.
• ddraw.h isn't being referenced in a way that allows the compiler to recognize the structure memberse.
• dsound.h isn't being referenced in a way that allows the compiler to recognize the structure memberse.
• We need a C replacment for init_event, this is relatet to the _cpp_init_ structures. C init #549

File issues

• appfat.cpp Byte-identical version of appfat_cpp_init. #110
  • delete is being overloaded
• capture.cpp
  • Looks like we are missing io.h
• diablo.cpp
  • looks like we need winuser.h
  • line 297 char szValueName[] = "Intro";
• missiles.cpp
  • unsigned char Dirs[16][16] = {...} needs to be rewritten in a C friendly way.
• movie.cpp (Compile movie.cpp as C #529)
  • LRESULT return type appears to not allow NULL, use 0?
• mpqapi.cpp Compile mpqapi.cpp as C #554
  • mpqapi_open_archive(const char *pszArchive, ...) first parameter gives the following errors C4028, C4090, C4024
• pfile.cpp
  • char password[16] = PASSWORD_SINGLE; needs to be rewritten in a C friendly way.
• wave.cpp
  • SFileReadFile(1,2,3,4,NULL) produce an error
• render.cpp
  • asm_* the C compiler is unhappy with the inline format. Make inline statments C compatible #550
  • asm_* dst & src are passed by references, this isn't allowed in C.
