java gdb 런타임

Question

java에서 process 객체를 사용하여 gdb 명령을 실행하는 방법은 무엇입니까? 내 자바 코드에서

charmae@charmae-pc:~/Desktop$ gcc -g file.c 
charmae@charmae-pc:~/Desktop$ gdb ./a.out

Process proc = rt.exec("gdb ./a.out"); 
       rt.exec("run"); 
BufferedReader std = new BufferedReader(new 
        InputStreamReader(proc.getErrorStream())); 
while ((s = std.readLine()) != null) { 
       System.out.println(s); 
       }

Yey! 내 자신의 질문에 대답했다. 나는 파이프 처리를 사용.

public class GDBpipeWriter 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 4"); 
     stdin.flush(); 
     stdin.println("break 10"); 
     stdin.flush(); 
     stdin.println("run"); 
     stdin.flush(); 

     /// write any other commands you want here 
     // 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 
     { 
      final byte[] buffer = new byte[1024]; 
      for (int 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_; 
}
