Re: [Boost-users] mutex locking!

4 Sep 2008


      i am trying to do the following but it says- error: 'class boost::mutex' has
no member named 'lock'


#include <boost/thread/mutex.hpp>

#ifndef __FO__
#define __FO__

class FO{
    private:
        int x;
        boost::mutex guard;
        void setGuard();
        void releaseGuard();
    public:
        boost::mutex mutexVar;
        //boost::detail::thread::lock_ops<boost::mutex> mylock;
        int getX();
        void setX(int);
        //FO();
};

#endif

#include "FO.h"

void FO::setGuard()
{
    guard.lock()

}

void FO::releaseGuard()
{
    guard.unlock();
}

int FO::getX()
{
    int tempX;
    setGuard();
    tempX=x;
    releaseGuard();
    return tempX;
}

void FO::setX(int tempX)
{
    setGuard();
    x=tempX;
    releaseGuard();
}

I want to explicitly lock and unlock mutex. Is it possible and what are
the methods?-- Wesley K
Yes, it's possible. boost::mutex implements the Lockable concept.
