用c++包装好的线程库,直接拿来使用,提高效率.

#include <thread.h>
#include <threads/semaphore.h>
#include <threads/exception.h>

#include <iostream>

using namespace std;
using namespace cpp_threads;

int main()
{
  Pthread::setProject( "/tmp/sematest" );
 Semaphore sem(attributes::process_shared_e);

 sem.wait();

 cout << "Got signal from semaphore.." << endl;
 exit(0);
}
