我試圖退出調試會話，並要求用戶輸入驗證。 我試圖在我的代碼Java GDB輸入不是來自終端
stdin.println("quit");
stdin.flush();
stdin.println("y"); // this does not work..
stdin.flush();
運行這段代碼，但它不工作..
如何使用這個Java外部程序我輸入發送給GDB？
public class Debugger extends Thread{
public void run(){
Process p = null;
try {
p = Runtime.getRuntime().exec("gdb a.out --interpreter=console");
new Thread(new SyncPipe(p.getErrorStream(), System.err)).start();
new Thread(new SyncPipe(p.getInputStream(), System.out)).start();
PrintWriter stdin = new PrintWriter(p.getOutputStream());
stdin.flush();
stdin.println("break main");
stdin.flush();
stdin.println("run");
stdin.flush();
stdin.println("s");
stdin.flush();
stdin.println("quit");
stdin.flush();
stdin.println("y"); // this does not work..
stdin.flush();
// stdin.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
class SyncPipe implements Runnable
{
public SyncPipe(InputStream istrm, OutputStream ostrm) {
istrm_ = istrm;
ostrm_ = ostrm;
}
public void run() {
try
{
int length;
byte[] buffer = new byte[1024];
for (length = 0; (length = istrm_.read(buffer)) != -1;){
ostrm_.write(buffer, 0, length);
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
private final OutputStream ostrm_;
private final InputStream istrm_;
}
