<p>You can (ab)use Pd's own symbol table by storing the clocks in a
"fake" Pd object and bind it to a symbol. But I wouldn't really
recommend this... </p>
<p>Alternatively, you can use one of the existing hash table
implementations in C, e. g. the hash table from the "stb" library:

<p>Or use C++ :-)</p>

<div>In Scheme for Max, the way I do it is I keep a hash-table
in C going with keys that are created on Scheme delay calls,
so that one can cancel clocks by fetching them from the
hashtable. In Max, there's a cross-platform hash-table
implementation that I'm using. Is there something similar for
Pd, or if not, is there an approach you would recommend for
keeping a key-value store in C for the clocks by a symbolic
key? I guess a good question might be if this is even
necessary, given there can't be *that* many clocks scheduled
for the future. And association list type thing might do just
as well.</div>

<div>thanks for the help, it's going well, now that I can
finally work on it! ought to have a first alpha folks can play
with in the next couple of weeks.</div>

is the only mechanism - for repeats, the easiest thing is
often<br>
to just re-use a clock() and re-set it each time it goes off
(as in<br>
the metro obejct). You can indeed create clock obejcts on the
fly -<br>
that's what pipe does. But you'll want to keep track of them
so you can<br>
cancel them if the owning object goes away.<br>
