DESCRIPTION

13       Only  a weaker sense of priorities is implemented, alluding to distinct
14       set of pros and cons compared to the stronger, strict approach to  them
15       as widely applied in this problem space (since the latter gives the ap‐
16       plication more control as  the  effect  of  the  former  can  still  be
17       achieved  with  some  reductions, whereas it is not straightforward the
18       other way around; cf. static  priority  task  scheduling  vs.  relative
19       fine-tuning within a single priority domain with nice(2)):
20
21       implicit mitigation for deadlock-prone priority arrangements
22
23       less  predictable (proportional probability based, we can talk about an
24       advisory effect of the priorities) responses  to  the  arrival  of  the
25       high-ranked  events  (i.e. in the process of the picking the next event
26       to handle from the priority queue when at least two  different  priori‐
27       ties are eligible at the moment)
28
29       One  practical  application  for this module of libqb is in combination
30       with IPC servers based on qbipcs.h published one (the qb_ipcs_poll_han‐
31       dlers  structure  maps  fittingly  to  the  control functions published
32       here).
