Folgender Fetzen Code gibt eine gescheite Fehlermeldung für streams (wann fixen die endlich streams & exceptions?)
auto fileName = std::string(getenv("HOME")) + "/config/clusterprocessaccounting.dat";
std::ofstream f(fileName);
if(not f) throw std::system_error(errno, std::system_category(), "failed to open " + fileName + " ");
terminate called after throwing an instance of 'std::system_error'
what(): failed to open /home/ite/config/clusterprocessaccounting.dat : No such file or directory
