[PD-dev] Using PD funcs from inside a threaded external

[B. Bogart]

Thanks for the comments Tim & Mathieu,

It seems I have two options:

* Not send output to PD (very limited functionality)

* Use Tim's suggestion.

Does this mean that rendering/audio in PD will be interrupted during
this time of global locking?

Ah! I would only need to lock while before I do the PD calls right?

Something like:

sys_lock();
outlet_symbol();
sys_unlock();

?

Thanks!
