int main()
{
std::vector<std::atomic_int> numbers(5);
for(int i = 0; i < 5; ++i)
std::atomic_init(&numbers[i], i);
return 0;
}
Dieses Programm liefert keine Fehlermeldung im Gegensatz zu
int main()
{
std::vector<std::atomic<int>> numbers(5);
for(int i = 0; i < 5; ++i)
std::atomic_init(&numbers[i], i);
}
Kann sein, dass der seperate Typ mehr bietet als std::atomic<int>, obwohl es nur ein typdef sein sollte. Ich bin der Sache aber nicht nachgegangen. Komplette Fehlermeldung:
