Problems using EnterCriticalSection

Question

I need to work with array from several threads, so I use CRITICAL SECTION to give it an exclusive access to the data.
Here is my template:

#include \"std         


        

Answer 1

I prefer using a separate Acquisition object over your code. Your code if fragile when an exception occurs between the Enter and Leave calls:

class CS_Acquire {
    CRITICAL_SECTION &cs;
public:
    CS_Acquire(CRITICAL_SECTION& _cs) : cs(_cs) { EnterCriticalSection(cs); }
    ~CS_Acquire() { LeaveCriticalSection(cs); }
};

Then in your class methods you would code it as:

template 
void SharedVector::PushBack(const T& value) {
   CS_Acquire acquire(&cs);
   vect.push_back(value);
}
