NAME

       qbloop.h - Main loop manages timers, jobs and polling sockets.

SYNOPSIS

       #include <qb/qbloop.h>

DESCRIPTION

       Only  a  weaker  sense  of priorities is implemented, alluding to distinct set of pros and
       cons compared to the stronger, strict approach to them as widely applied in  this  problem
       space (since the latter gives the application more control as the effect of the former can
       still be achieved with some reductions, whereas it is not straightforward  the  other  way
       around;  cf.  static  priority  task  scheduling  vs. relative fine-tuning within a single
       priority domain with nice(2)):

       implicit mitigation for deadlock-prone priority arrangements

       less predictable (proportional probability based, we can talk about an advisory effect  of
       the priorities) responses to the arrival of the high-ranked events (i.e. in the process of
       the picking the next event to handle from the priority queue when at least  two  different
       priorities are eligible at the moment)

       One  practical  application  for  this  module of libqb is in combination with IPC servers
       based on qbipcs.h published one (the qb_ipcs_poll_handlers structure maps fittingly to the
       control functions published here).
