Description

The named mutex is created before the hibernate, then opened after the hibernate, when I was debugging, the debugger would go back to another thread when opening the mutex.

Could you specify a bit more the error? The mutex can't be opened after the hibernation? The mutex disappears?

I've put try...catch around the mutex too as it may be throwing an exception and that's why it was going back to the other thread, although I didn't look in the debug output. Will test it in a standalone program tonight.

using namespace boost::interprocess; using namespace std;

int main(int argc, char argv[]) {

try {

named_mutex nm(create_only,"testmtx");

}

catch(interprocess_exception &ex){

cout<< ex.what() <<endl;

}

string s; cin>> s; pause to allow hibernation try{ named_mutex nm(open_only,"testmtx"); }

catch(interprocess_exception &ex){

cout<< ex.what() <<endl; The system cannot find the file specified.

}

return 0;

}
