Hallo devs!
In m_sched.c, line 383, there is the following declaration:
--------------8<---------8<----------
/* sys_idlehook is a hook the user can fill in to grab idle time. Return
nonzero if you actually used the time; otherwise we're really really
idle and
will now sleep. */
int (*sys_idlehook)(void);
-------8<------------8<--------------
which get's called in line 483:
--------8<---------8<--------------
/* call externally installed idle function if any. */
if (!sys_idlehook || !sys_idlehook())
{
/* if even that had nothing to do, sleep. */
if (timeforward != SENDDACS_SLEPT)
sys_microsleep(sys_sleepgrain);
}
-----------8<--------------8<------
So, I'm not really sure, how to use this callback ...
If I write e.g. an external which uses this callback, how am I sure,
that the specific function will be executed ?
Because in an other external, thread, or whatever, I could simply assign
to that callback an other function !? because there is only a callback
for one function ? (or am I thinking in a wrong direction ?)
(and I didn't find an example that uses this callback ... if there is
one please let me know)
Thanks,
LG

PS: and yes I know there are the idle callbacks in devel which do
exactly this - but how to do it in the current pd ?
