Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    FileOutputStream os = new FileOutputStream("outfilename");
    FileDescriptor fd = os.getFD();
    os.write(1);
    os.flush();//from w  w  w .  ja v  a  2 s  .c  o m
    fd.sync();
}

From source file:Main.java

public static void main(String[] argv) throws Exception {

    os.flush();/*from w  ww.ja  va2  s  . com*/
    fd.valid();
}

From source file:Main.java
