Push to front of process queue (proc_queue_push_front)

Declaration​

size = proc_queue_push_front(key, value)

Parameters​

  • key
    String.
  • value
    String. The value to push.

Returns​

  • size
    Integer. Size after pushing. If 0, push failed.

Notes​

  • All process queues whose names start with "xxtouch." or "1ferver." are preserved.
  • Queue size must not exceed 10000; exceeding values will drop earliest entries.
  • Push a value to the front and return the size.
  • Empty string cannot be pushed.

Example​

local size = proc_queue_push_front("billnos", "name")
if size ~= 0 then
    print("has "..size.." bill(s)")
else
    print("failed")
end
