Can anyone show me how to make use of a FileDescriptor?
For eg. how do I replace it for the parameter of the FileInputStream constructor?
FileInputStream inputStream = new FileInputStream("C:/test.txt");

best regards,<br />Steven<br />SCJP, SCEA

I'm not too sure about what you are asking exactly, however I found this on the web that might help you.

Good Luck.

I got it oredi, Mario.

public static void main(String a[])
FileDescriptor fd = new FileDescriptor();
FileInputStream fI = new FileInputStream(fd.in);
FileOutputStream fO = new FileOutputStream(fd.out);
int c;
while((c=fI.read()) != -1)
catch(IOException e){e.printStackTrace();}
It is sorta covered in the JavaRanch Style Guide.
