Dear all,
I found that the definition of the IMAGE_RUNTIME_FUNCTION_ENTRY
structure differs between the winnt.h header supplied with Cygwin and
the one supplied from the Microsoft SDK (v7.1).
Cygwin gives me this in /usr/include/w32api/winnt.h:
typedef struct _IMAGE_RUNTIME_FUNCTION_ENTRY {
DWORD BeginAddress;
DWORD EndAddress;
PVOID ExceptionHandler;
PVOID HandlerData;
DWORD PrologEndAddress;
} IMAGE_RUNTIME_FUNCTION_ENTRY,*PIMAGE_RUNTIME_FUNCTION_ENTRY;
In "C:\Program Files\Microsoft SDKs\Windows\v7.1\Include\WinNT.h", on
the other hand, I find:
typedef struct _IMAGE_RUNTIME_FUNCTION_ENTRY {
DWORD BeginAddress;
DWORD EndAddress;
DWORD UnwindInfoAddress;
} _IMAGE_RUNTIME_FUNCTION_ENTRY, *_PIMAGE_RUNTIME_FUNCTION_ENTRY;
...
typedef _IMAGE_RUNTIME_FUNCTION_ENTRY IMAGE_RUNTIME_FUNCTION_ENTRY;
typedef _PIMAGE_RUNTIME_FUNCTION_ENTRY PIMAGE_RUNTIME_FUNCTION_ENTRY;
Clearly, these definitions are incompatible. Binary dumping of the
.pdata section of a PE image strongly suggests that the Windows SDK is
correct on this one.
Any idea where Cygwin's version came from? Should it be corrected/could
you correct it? And while it hasn't been corrected, is there some easy
way to use the SDK's version of the headers or should I just copy the
definition?
With kind regards,
Erik
