interprocess named_mutex does not survive hibernate

[Jan Stetka <jan.stetka@…>]

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?

[Jan Stetka <jan.stetka@…>]

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.

#define BOOST_DATE_TIME_NO_LIB #include "boost\interprocess\sync\named_mutex.hpp" #include <string> #include <iostream>

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;

}

Fixed for Boost 1.45 in release branch
