new-fifo initializes new FIFO <list> (First In First Out). <list> is a pointer to type
"vely_fifo", and can be created with optional
"define".
FIFO <list> contains key/value pairs on a first-in, first out basis. It is useful for storing temporary information in memory which can be quickly retrieved. Note that a list is accessible to the current process only.
Generally pairs of key/value are stored in a FIFO list, and retrieved (possibly many times) in the same order in which they were stored.
The internal positions for
write-fifo and
read-fifo actions are separate so you can keep adding data to the list, and obtain it in any number of retrieval passes by using
rewind-fifo.
