std::vector, thread-safety, multi-threading

Question

I am using std::vector as shared data in a multi-threaded application. I encapsulate the thread inside a class, e.g.,

class ABC {
public:
    double a, b, c         


        

Answer 1

You call ptrVector->size() without locking it first. This could easily be the cause of your problems. Make sure to lock your vector before any reads or writes.
