I note (now :-) that QueueAsyncCall() works on a strictly LIFO
basis, i.e. it's really a stack rather than a queue.
Has anybody ever built a simple round-robin scheduler based on this,
for example to handle low-speed comms on an indeterminate number of
serial ports?
Which revision of lazarus? IIRC it was very recently changed
(corrected) to FIFO.
0.9.28.3. I saw the discussion from earlier in the year, but I was
specifically considering code that could handle several serial ports
pseudo-concurrently while being able to display messages etc. using
visual controls. Obviously I could go for a full-blooded multithreaded
solution, but async calls work very well for one port at a time...
Maybe look at trunk, I don't know if that ever went into any branch.
