// Questions
Hi there,
Please I need advice on the following subjects:

1- Some macro #defines are deficult to implement in D. eg.:
 #define rvaDLLName  szName
 Is there any other way than doing global search and replace?

2- How I can implement template functions in D. eg.:
 in C++:
 template <class T> void DumpOptionalHeader(T* pImageOptionalHeader);
 I converted it to:
 template DumpOptionalHeader(T = IMAGE_OPTIONAL_HEADER32) {
 void DumpOptionalHeader(T* pImageOptionalHeader)  // 'T' is
IMAGE_OPTIONAL_HEADER32/64
 { ... } }
 Is this right? or is there any beter way?

3- The following code compile in C++ but not in D and compiler give outside
array bounds error. why?
 in C++:
 typedef struct DATASYM32 {
  unsigned short  reclen;         // Record length
  unsigned short  rectyp;         // S_LDATA32, S_GDATA32 or S_PUB32
  CV_uoff32_t     off;
  unsigned short  seg;
  CV_typ_t        typind;         // Type index
  unsigned char   name[1];        // Length-prefixed name
 } DATASYM32;
 typedef DATASYM32 PUBSYM32;

 PCSTR pszUndecoratedName = (PCSTR)&pDataSym32->name[1]; // < == NOTE this

 I converted it to but the markered array line give outside array bounds
error [0..1]
 struct DATASYM32 {
     ushort  reclen;         // Record length
     ushort  rectyp;         // S_LDATA32, S_GDATA32 or S_PUB32
     CV_uoff32_t     off;
     ushort  seg;
     CV_typ_t        typind;         // Type index
     ubyte   name[2];        // Length-prefixed name // originally, it was
name[1] but the code below
         // gives outside of array bounds error although it compiles wright
in C++. ??!!!
 } ;
 alias DATASYM32 PUBSYM32;


 PCSTR pszUndecoratedName = cast(PCSTR)&pDataSym32.name[1];

4- about primitive types in C++ is:
 unsigned long => ulong or uint ?
 and other types, and it's equivelent in d ?

5- Is there any documentation or references about OMF lib format on the
internet. maybe I can relate the data
 structures with the new Microsoft COFF archive format!

looks ok to me

I don't know why it failed - one would think declaring name[2] would allow
name[1] to be dereferenced.

 4- about primitive types in C++ is:
  unsigned long => ulong or uint ?
  and other types, and it's equivelent in d ?


it depends. see the D doc. typically in C long is 32 bits. "long long" is
64.

 5- Is there any documentation or references about OMF lib format on the
 internet. maybe I can relate the data
  structures with the new Microsoft COFF archive format!


try googling. I don't have any references handy.
