How do I get at the exception information when using MiniDumpWriteDump out-of-process?

by

You also need the MINIDUMP_EXCEPTION_INFORMATION.ThreadId value. The simplest way, and the way I made it work, is to use a memory-mapped file to transfer both the ThreadId and the ExceptionPointers. And a named event to wake up the watchdog. It doesn’t matter that the pointer is not valid in the context of the watchdog process.

Use CreateFileMapping + MapViewOfFile in the watched process as part of its initialization, OpenFileMapping + MapViewOfFile in the watchdog. Your SetUnhandledExceptionFilter should then only call GetCurrentThreadId() and copy the tid and the pExcept to the memory mapped file view, call SetEvent() to wake up the watchdog and block forever until the watchdog terminates it.
