At some point in Sofia history, there was extern there.

If you don't write it, it doesn't have it.. I've always thought that the function called by Windows dynamic loader would be DllMain. D'oh. This seems to be a bit more complicated. Quick googling revealed that normally C runtime includes its own initialization code in DLLs as DllMainCRTStartup() and this initialization code invokes constructors, prepares for destructors and then calls DllMain: <http://support.microsoft.com/kb/94248> <http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/mingw/dllcrt1.c?rev=1.4&cvsroot=src> (looks like _pei386_runtime_relocator() is the thing that I've been missing all these years. Damn MS. Damn DllMainCRTStartup()). This looks like the way to implement __attribute__((destructor)) with MSVC: <http://www.codeguru.com/cpp/misc/misc/threadsprocesses/article.php/c6945> -- Pekka.Pessi mail at nokia.com ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
