1、调用的函数定义

typedef BOOL (*MiniDumpWriteDump_PTR)(
                                      HANDLE hProcess,
                                      DWORD ProcessId,
                                      HANDLE hFile,
                                      MINIDUMP_TYPE DumpType,
                                      PMINIDUMP_EXCEPTION_INFORMATION ExceptionParam,
                                      PMINIDUMP_USER_STREAM_INFORMATION UserStreamParam,
                                      PMINIDUMP_CALLBACK_INFORMATION CallbackParam
                                      );

void CreateMiniDump(struct _EXCEPTION_POINTERS* ExceptionInfo)
{
   HMODULE hModule = ::LoadLibrary(_T(".\\dbghelp.dll"));
   if( NULL == hModule )
       return;
   MiniDumpWriteDump_PTR pfnMiniDumpWriteDump = (MiniDumpWriteDump_PTR)GetProcAddress(hModule, "MiniDumpWriteDump");
   if( NULL == pfnMiniDumpWriteDump )
   {
       FreeLibrary(hModule);
       return;
   }
   TCHAR szFile[MAX_PATH+1] = {0};
   _sntprintf_s(szFile, sizeof(szFile),MAX_PATH, _T(".\\control_%u.dmp"), time(NULL));
   HANDLE hFile = CreateFile(szFile, GENERIC_ALL, FILE_SHARE_READ, NULL, CREATE_ALWAYS, 0, NULL);
   if( INVALID_HANDLE_VALUE == hFile )
   {
       FreeLibrary(hModule);
       return;
   }
   MINIDUMP_EXCEPTION_INFORMATION mei;
   mei.ThreadId = GetCurrentThreadId();
   mei.ClientPointers = TRUE;
   mei.ExceptionPointers = ExceptionInfo;

   (*pfnMiniDumpWriteDump)(GetCurrentProcess(), GetCurrentProcessId(), hFile,
       MiniDumpWithFullMemory,
       &mei, NULL, NULL);
   CloseHandle(hFile);
   FreeLibrary(hModule);
}
LONG WINAPI CCCtrl_UnhandledExceptionFilter(
struct _EXCEPTION_POINTERS* ExceptionInfo
   )
{
   OutputDebugString(_T("ESCControl meet unhandled SEH exception! Quit!\n"));
   CreateMiniDump(ExceptionInfo);

   ::SetErrorMode(SEM_NOGPFAULTERRORBOX);
   ::ExitProcess(1);
   return EXCEPTION_EXECUTE_HANDLER;
}

2、一般放在main函数的第一行

#ifndef _DEBUG
   ::SetUnhandledExceptionFilter(CCCtrl_UnhandledExceptionFilter);
#endif
