Remove the existing timeout on key, turning the key from volatile (a key with an expire set) to persistent (a key that will never expire as no timeout is associated).

Reply

One of the following:

• Integer: 0 if key does not exist or does not have an associated timeout.
• Integer: 1 if the timeout has been removed.
