/* Windows32 threads specific definitions. The windows32 threading model
|
|
|
|
does not map well into pthread-inspired gcc's threading model, and so
|
|
|
|
there are caveats one needs to be aware of.
|
|
|
|
|
|
|
|
1. The destructor supplied to __gthread_key_create is ignored for
|
|
|
|
generic x86-win32 ports. This will certainly cause memory leaks
|
|
|
|
due to unreclaimed eh contexts (sizeof (eh_context) is at least
|
|
|
|
24 bytes for x86 currently).
|
|
|
|
|
|
|
|
This memory leak may be significant for long-running applications
|
|
|
|
that make heavy use of C++ EH.
|
|
|
|
|
|
|
|
However, Mingw runtime (version 0.3 or newer) provides a mechanism
|
|
|
|
to emulate pthreads key dtors; the runtime provides a special DLL,
|
|
|
|
linked in if -mthreads option is specified, that runs the dtors in
|
|
|
|
the reverse order of registration when each thread exits. If
|
|
|
|
-mthreads option is not given, a stub is linked in instead of the
|
|
|
|
DLL, which results in memory leak. Other x86-win32 ports can use
|
|
|
|
the same technique of course to avoid the leak.
|
|
|
|
|
|
|
|
2. The error codes returned are non-POSIX like, and cast into ints.
|
|
|
|
This may cause incorrect error return due to truncation values on
|
|
|
|
hw where sizeof (DWORD) > sizeof (int).
|
|
|
|
|
2004-04-27 23:38:05 +02:00
|
|
|
3. We are currently using a special mutex instead of the Critical
|
|
|
|
Sections, since Win9x does not support TryEnterCriticalSection
|
|
|
|
(while NT does).
|
