Win32 线程的创建&信号量临界资源&事件对象

背景：

写了个程序，主要实现的功能为主线程创建两个子线程，之后主线程进入等待事件的循环。子线程1对临界资源cnt的值减2并输出cnt的值。子线程2对cnt的值加1并输出cnt的值，且当cnt为50的时候触发事件对象hend_even，子进程2退出。主线程收到hend_even后杀死子线程1，之后进入scanf阻塞。。。

代码示例：

运行结果：

thread a delete 2 of cnt = 98

thread b add 1 of cnt = 99

thread a delete 2 of cnt = 97

thread b add 1 of cnt = 98

thread a delete 2 of cnt = 96

thread b add 1 of cnt = 97

thread a delete 2 of cnt = 95

thread b add 1 of cnt = 96

thread a delete 2 of cnt = 94

thread b add 1 of cnt = 95

thread a delete 2 of cnt = 93

thread b add 1 of cnt = 94

thread a delete 2 of cnt = 92

thread b add 1 of cnt = 93

thread a delete 2 of cnt = 91

thread b add 1 of cnt = 92

thread a delete 2 of cnt = 90

thread b add 1 of cnt = 91

thread a delete 2 of cnt = 89

thread b add 1 of cnt = 90

thread a delete 2 of cnt = 88

thread b add 1 of cnt = 89

...

thread a delete 2 of cnt = 51

thread b add 1 of cnt = 52

thread a delete 2 of cnt = 50

thread b add 1 of cnt = 51

thread a delete 2 of cnt = 49

thread b add 1 of cnt = 50

proc b stop to sail ticket...

back to main thread...
