Provided by: libqb-dev_2.0.8-2_amd64 bug

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).
