i，后面打印也是null，后面查阅了资料system()函数只是提供了一个接口的作用，所以共享内存的方法来接收数据不太现实，这里换了一个匿名管道的方式接收数据 匿名管道的实现代码如下 HANDLE hRead...CreatePipe(&hRead,&hWrite,&sa,0)) { printf("CreatePipe...si.dwFlags = STARTF_USESTDHANDLES; si.hStdInput = hRead...::ReadFile(hRead, lpsRetBuffer, 4096, &RetBufferSize, NULL)) { printf("Readfile failed, error is :...%d", GetLastError()); return FALSE;}CloseHandle(hRead);CloseHandle(pi.hProcess);CloseHandle(pi.hThread

hread 的源码中定义了6种状态：new（新建）、runnnable（可运行）、blocked（阻塞）、waiting（等待）、time waiting （定时等待）和 terminated（终止）。
hread t = Thread.currentThread(); ThreadLocalMap map = getMap(t); map.set(this, value); 要能够完成多线程的协调工作
