Hi all,
Recently I am reading codes of libmemlif (based on vpp19.01) ,I
am a little bit confused about the fields of head/tail in struct memif_ring_t
and last_head/last_tail in struct memif_queue_t.
Can anybody help to clarify the internal mechanism of the
read/write operation of ring and how to move the head/tail and
last_head/last_tail? I'd like to better understand this and really appreciate
if anyone can help.
BRs,
Kevin
