Я пытаюсь создать инструмент для моих конечных пользователей, который может создать MiniDump моего приложения, если оно зависает (то есть вне приложения).Я использую тот же код, что и внутренний MiniDumper, но с дескриптором и processid приложения, но я продолжаю получать код ошибки 0xD0000024 при вызове MiniDumpWriteDump.Любые идеи?
void produceDump( const char* exe )
{
DWORD processId = 0;
HANDLE process = findProcess(exe, processId);
if (!process || processId == 0)
{
printf("Unable to find exe %s to produce dump.\n", exe);
return;
}
LONG retval = EXCEPTION_CONTINUE_SEARCH;
HWND hParent = NULL; // find a better value for your app
// firstly see if dbghelp.dll is around and has the function we need
// look next to the EXE first, as the one in System32 might be old
// (e.g. Windows 2000)
HMODULE hDll = NULL;
char szDbgHelpPath[_MAX_PATH];
if (GetModuleFileName( NULL, szDbgHelpPath, _MAX_PATH ))
{
char *pSlash = _tcsrchr( szDbgHelpPath, '\\' );
if (pSlash)
{
_tcscpy( pSlash+1, "DBGHELP.DLL" );
hDll = ::LoadLibrary( szDbgHelpPath );
}
}
if (hDll==NULL)
{
// load any version we can
hDll = ::LoadLibrary( "DBGHELP.DLL" );
}
LPCTSTR szResult = NULL;
int err = 0;
if (hDll)
{
MINIDUMPWRITEDUMP pDump = (MINIDUMPWRITEDUMP)::GetProcAddress( hDll, "MiniDumpWriteDump" );
if (pDump)

if (hFile!=INVALID_HANDLE_VALUE)
{

mci.CallbackRoutine = (MINIDUMP_CALLBACK_ROUTINE)MyMiniDumpCallback;
mci.CallbackParam = 0;
MINIDUMP_TYPE mdt = (MINIDUMP_TYPE)(MiniDumpWithPrivateReadWriteMemory |
MiniDumpWithDataSegs |

// write the dump
BOOL bOK = pDump( process, processId, hFile, mdt, NULL, NULL, &mci );
DWORD lastErr = GetLastError();
if (bOK)

}
этот код работает на 100%, когда его внутренний для процесса (т.е. с SetUnhandledExceptionFilter)
