i dunno if this is what you want, but it'll work.

class Callback
{
public:
  virtual bool operator()(int progress, int total)=0;
};

class VeryLongProcess
{
public:
    VeryLongProcess(Callback *pCB) : m_pCB(pCB {}

    void doit();
private:
    Callback *m_pCB;
};


void VeryLongProcess::doit()
{
    for(int i = 0; i < VLP_ITERATIONS; i++)
    {
        if(!(i&0x7f)) // every 128 iterations
        {
          if(!(*m_pCB)(i, VLP_ITERATIONS))
          {
            break; // abort
          }
        }
        // ... do actual work here
    }

    if (i != VLP_ITERATIONS)
    {
      // we aborted, do abort cleanup
    }
}
