Detailed Description

A Mutex wrapper. Based on pthread calls.

Note

Using this implementation one can create a thread -safe singleton:

class Singleton
{
     public:
         static Singleton& Instance();
         int example_data;
         ~Singleton() { }
     protected:
         Singleton(): example_data(42) { }
     private:
         static std::auto_ptr<Singleton> theSingleInstance;
         static Mutex m;
};

Singleton& Singleton::Instance()
{
     MutexLocker obtain_lock(m);
     if (theSingleInstance.get() == 0)
         theSingleInstance.reset(new Singleton);
     return *theSingleInstance;
}

std::auto_ptr<Singleton> Singleton::theSingleInstance;
Mutex Singleton::m;

#include <cstdio>
int main()
{
     printf("%d\n", Singleton::Instance().example_data);
     return 0;
}
