Create FIFO list.
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
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
