2340 However, debugger support (libomp_db) cannot work with handles, because they
2341 uncomparable. For example, debugger requests info about thread with handle h.
2342 h is valid within debugger process, and meaningless within debugee process.
2343 Even if h is duped by call to DuplicateHandle(), so the result h' is valid
2344 within debugee process, but it is a *new* handle which does *not* equal to
2345 any other handle in debugee... The only way to compare handles is convert
2346 them to system-wide ids. GetThreadId() function is available only in
2347 Longhorn and Server 2003. :-( In contrast, GetCurrentThreadId() is available
2348 on all Windows* OS flavours (including Windows* 95). Thus, we have to get
2349 thread id by call to GetCurrentThreadId() from within the thread and save it
2350 to let libomp_db identify threads. */
