<p>Hi,</p>
<p>this is a bit of a XY question. The actual problem is about
managing clocks. Let's see if we can find a proper solution.<br>
</p>
<p>I would assume that you are storing the clock(s) alongside the
interpreter instance. If you restart the interpret, unset the
clock(s) with clock_unset(). If you free the instance, free the
clock(s) with clock_free().</p>
<p>If that somehow doesn't work for you, explain the exact problem
and show the code.<br>
</p>
<p>---</p>
<p>> It doesn't need to be unique across the world, just the
local machine</p>
<p>Why would your ID even need to be unique across the whole
machine? I think it should be enough that it's unique within the
app. In that case, you can simply use the memory address of the
interpreter instance itself. In fact, that's how Pd creates the
canvas and object IDs for communicating with the Tcl/Tk GUI app.</p>

<div dir="ltr">Hi folks, i'm wrestling away with the schedule
functions for Scheme-for-Pd, and I think I can make things a lot
more reliable if I let every instantiation (or restart) of the
scheme interpreter have a uid of some sort so that on a reset we
can just ignore clocks running out on a previous instance
instead of trying to clean them all up with manual memory
management. (which approach is giving me segfaults because I'm
screwing something up)

<div>Can anyone tell me what a smart way of getting a unique
identifier would be? It doesn't need to be unique across the
world, just the local machine, so something that was seeded
from system time would be fine. I'm not a Real C Programmer
though, so am not clear what options will just work across all
OS's, without needing to add dependencies.</div>
