How to set timeout forever

How can I set a timeout forever? like below

Timeout t;
void flip(){
//flip code here
}
void main(){
t.attach(&flip, ?);
}

Hello,

if you want to do this, maybe Ticker is better.
With the Timeout you have to re-attach it at every end of your function.

Timeout t;

void flip(){
  //flip code here

  // re-attach it 
  t.attach(&flip, ?);
}

void main(){
  t.attach(&flip, ?);
  // rest of code
}
