Hey is the recruitment going on for freshers in india???

@megha
stop asking this junk question. i've noticed this kinda junk question being asked in many threads, please avoid that. we're here to solve/discuss about the problem at hand. you would be better off asking such questions to your friends.

@megha absolutely correct

//Use double-check pattern with a bool member variable to make it thread safe
Instance *getInstance(){
if ( available ){
pthread_lock(mtx);
if ( available ){
_instance = new Singleton();
available = true;
}
}
}

typo in the previous post
//Use double-check pattern with a bool member variable to make it thread safe
Instance *getInstance(){
if ( available ){
pthread_lock(mtx);
if ( available ){
_instance = new Singleton();
available = true;
}
}
return _instance;
}

IN Java, use synchronised keyword on the static function which returns the singleton object

bullshit question
