Compilation error " Cannot convert parameter from 'int' to 'HANDLE' "
occurs
on 64 bit windows for stackwalk64 code. I am porting 32 bit code to 64 bit
windows. Could you please any one tell me why compiler is throwing these
errors ? MS VS2005 is being used. Down below is code snippet.

stackwalkerTest.h
-----------------
typedef BOOL (__stdcall * STACKWALKPROC)
( DWORD, HANDLE, HANDLE, LPSTACKFRAME, LPVOID,
PREAD_PROCESS_MEMORY_ROUTINE,PFUNCTION_TABLE_ACCESS_ROUTINE,
PGET_MODULE_BASE_ROUTINE, PTRANSLATE_ADDRESS_ROUTINE );

typedef DWORD (__stdcall *SYMSETOPTIONSPROC)(DWORD);

typedef BOOL (__stdcall *SYMGETSYMFROMADDRPROC)
( HANDLE, DWORD, PDWORD, PIMAGEHLP_SYMBOL );
typedef BOOL (__stdcall *SYMGETLINEFROMADDRPROC)
( HANDLE, DWORD, PDWORD, PIMAGEHLP_LINE );
typedef BOOL (__stdcall * SYMINITIALIZEPROC)( HANDLE, LPSTR, BOOL );
typedef BOOL (__stdcall *SYMCLEANUPPROC)( HANDLE );
typedef LPVOID (__stdcall *SYMFUNCTIONTABLEACCESSPROC)( HANDLE, DWORD );
typedef DWORD (__stdcall *SYMGETMODULEBASEPROC)( HANDLE, DWORD );

STACKWALKPROC _StackWalk;

You used a reserved word.

SYMSETOPTIONSPROC _SymSetOptions;

And again.

SYMGETSYMFROMADDRPROC _SymGetSymFromAddr;
SYMGETLINEFROMADDRPROC _SymGetLineFromAddr;
SYMINITIALIZEPROC _SymInitialize;
SYMCLEANUPPROC _SymCleanup;
SYMFUNCTIONTABLEACCESSPROC _SymFunctionTableAccess;
SYMGETMODULEBASEPROC _SymGetModuleBase;

And a few more times.

stackwalkerTest.cpp
-------------------

if ( ! _StackWalk64( IMAGE_FILE_MACHINE_AMD64,
                           GetCurrentProcess(),
                           GetCurrentThread(),
                           &sf,
                           pContext,
                           0,
                           _SymFunctionTableAccess,
                           _SymGetModuleBase,
                           0 ) )

shouldn't that be (after fixing your variable name)?

if (! (*pfnStackWalk)( IMAGE_FILE_MACHINE_AMD64, ... ) )

{
....
}
