C + + uses CriticalSection to implement thread synchronization instances _c languages

This article describes the C + + using CriticalSection method to implement thread synchronization, in the previous C + + thread synchronization case analysis based on the addition of four lines of code, the use of four functions:
EnterCriticalSection::D eletecriticalsection:: entercriticalsection:: LeaveCriticalSection At this time, the number printed out is equal.

The specific code is as follows:

#include "stdafx.h" 
#include <Windows.h> 
 
DWORD g_cnt1; 
DWORD G_cnt2; 
BOOL g_bcontinue = TRUE; 
Critical_section CS; 
 
DWORD WINAPI ThreadProc (__in lpvoid lpparameter) 
{ 
  :: EnterCriticalSection (&CS); 
  while (g_bcontinue) 
  { 
    g_cnt1++; 
    g_cnt2++ 
  } 
  :: LeaveCriticalSection (&CS); 
  return 0; 
} 
 
int _tmain (int argc, _tchar* argv[]) 
{ 
  HANDLE hthread[2]; 
  g_cnt1 = G_cnt2 = 0; 
  :: InitializeCriticalSection (&CS); 
 
  Hthread[0] =:: CreateThread (NULL, 0, threadproc, NULL, 0, NULL); 
  HTHREAD[1] =:: CreateThread (NULL, 0, threadproc, NULL, 0, NULL); 
 
  Sleep (1000); 
  G_bcontinue = FALSE; 
  :: WaitForMultipleObjects (2, Hthread, TRUE, INFINITE); 
  printf ("g_cnt1=%d\n", g_cnt1); 
  printf ("g_cnt2=%d\n", G_cnt2); 
 
  ::D eletecriticalsection (&CS);: 
 
  : CloseHandle (Hthread[0]);:: 
  CloseHandle (hthread[1]); 
  return 0; 
}

I hope this article will help you with the C + + program design.
