Accessing Data Members in a Multithreaded Application

Accessing Data Members in a Multithreaded Application

To ensure that only a single thread accesses a data member of an object, declare that member private. Next, add the necessary synchronization operations (e.g., a call to EnterCriticalSection()) in the “getter” and “setter” member functions before actually accessing that member. Finally release the lock (e.g., by calling LeaveCriticalSection()) before the function returns:

 class Person{ string name;public: void setName(const string& newname) {  EnterCriticalSection();  name=newname;  LeaveCriticalSection } void getName(string& firstname) const {  EnterCriticalSection();  firstname=name;  LeaveCriticalSection }};
