Purge fifo

Purpose: Delete FIFO list data.

 purge-fifo <list>

purge-fifo will delete all elements from the FIFO <list>, created by new-fifo. The list is then empty and you can still put data into it, and get data from it afterwards, without having to call new-fifo again.

All keys or values stored in the list are also deleted.
Examples
See read-fifo.
