We continue coping with pointers, and our next task is to reference count an array. Let's take a look at the program that gets some data from the stream and processes it in different threads. The code to do this is as follows:

#include <cstring> 
#include <boost/thread.hpp> 
#include <boost/bind.hpp> 
 
void do_process(const char* data, std::size_t size); 
 
void do_process_in_background(const char* data, std::size_t size) { 
    // We need to copy data, because we do not know, 
    // when it will be deallocated by the caller.
    char* data_cpy = new char[size]; 
    std::memcpy(data_cpy, data, size); 
 
    // Starting thread of execution to process data.
    boost::thread(boost::bind(&do_process, data_cpy, size)) 
            .detach(); 
    boost::thread(boost::bind(&do_process, data_cpy, size...
