临界区线程死锁代码示例：

#include <windows.h>#include <iostream>using namespace std; DWORD WINAPI Fun1Proc(LPVOID lpParameter );DWORD WINAPI Fun2Proc(LPVOID lpParameter ); CRITICAL_SECTION g_csA;CRITICAL_SECTION g_csB;int tickets=100; void main(){ HANDLE hThread1; HANDLE hThread2; hThread1=CreateThread(NULL,0,Fun1Proc,NULL,0,NULL); hThread2=CreateThread(NULL,0,Fun2Proc,NULL,0,NULL); CloseHandle(hThread1); CloseHandle(hThread2); InitializeCriticalSection(&g_csA); InitializeCriticalSection(&g_csB); Sleep(1); DeleteCriticalSection(&g_csA); DeleteCriticalSection(&g_csB); }DWORD WINAPI Fun1Proc(LPVOID lpParameter){ while(true){ EnterCriticalSection(&g_csA); Sleep(1); EnterCriticalSection(&g_csB); if(tickets>0){ Sleep(1); cout<<"Thread1 sell ticket:"<<tickets--<<endl; LeaveCriticalSection(&g_csA); LeaveCriticalSection(&g_csB); } else{ LeaveCriticalSection(&g_csA); LeaveCriticalSection(&g_csB); break; } } return 0;}DWORD WINAPI Fun2Proc(LPVOID lpParameter){ while(true){ EnterCriticalSection(&g_csB); Sleep(1); EnterCriticalSection(&g_csA); if(tickets>0){ Sleep(1); cout<<"Thread2 sell ticket:"<<tickets--<<endl; LeaveCriticalSection(&g_csA); LeaveCriticalSection(&g_csB); } else{ LeaveCriticalSection(&g_csA); LeaveCriticalSection(&g_csB); break; } } return 0;}
