help with input/output redirection

[Hard_Working_]

Hi everyone, I wonder if someone can help me:

In order to implement a pipe, I redirected stdin into the pipe...

close(0);
dup(m[0]);
...

My problem is, after i use the pipe, I want to continue the execution, using stdin normally (reading from the keyboard just like before).

But, even if close the pipe, I can not recover stdin to 0...

How can I do this? please post the line of code that recovers it...

Thank you very much

If you do a

close(0)

Do you try to do something like

open(0)

again?
