Hello, all ... OK, i'm experiencing a crash every now and then (WIndows) and all-the- freakin'-time (Mac OSX) for my app. Looking into it, I see this, which I wrote before I understood the beauty of scoped_ptr: template< class T > class Thread { public: Thread() : pBoostThread( NULL ), pThreadFunction( NULL ), m_ExitSignal( false ) {} return_status Init( return_status ( *pFunc )( Thread * ), T varArg ) { pThreadFunction = pFunc; varThreadArg = varArg; return SUCCESS; } return_status Start() { pBoostThread = new boost::thread( boost::bind( pThreadFunction, this ) ); return SUCCESS; } . . . return_status Exit( unsigned long exit_code ) { . . . if ( pBoostThread ) delete pBoostThread; // ouch!!! . . . } }; I tried wrapping the icky "new boost::thread< ... >" in a boost::scoped_ptr, like so: pBoostThread = new boost::scoped_ptr< boost::thread( boost::bind ( pThreadFunction, this ) ) >; ... but the compiler didn't like it (boost::bind cannot appear inside a constant expression). What is the proper way of wrapping a boost::thread in a scoped_ptr? My boost::thread has to be on the heap, because the function pointer assigned to it is defined _after_ the Thread class is instantiated. Any help would be appreciated greatly :-) Regards, John Falling You - exploring the beauty of voice and sound http://www.fallingyou.com
